I am new to Ubuntu which I have installed via Virtualbox on my iMac, Ubuntu 24.04.4 according to terminal. I am having a couple of problems with the Show Apps app on the tray.

First the captions on the various apps are not fully spelt out.

I see apps captioned "Blu..." "Bra..." etc.

Second question is : which particular apps I actually have ?

Now I know there is an app called "Ubuntu Software" with an icon of an orange briefcase with a large capital 'A' on it.

However I do NOT have this app.

I started at the ProtonVPN site specifically for Linux Mint and followed their process. I got a "package not found" error. In the process, however, I ended up installing dependencies (I believe). Then I tried this recommended command:

sudo apt upgrade
wget -q -O - https://repo.protonvpn.com/debian/public_key.asc | sudo apt-key add -
sudo add-apt-repository 'deb https://repo.protonvpn.com/debian unstable main'
sudo apt update && sudo apt install protonvpn

This installed successfully (without errors, that is). But I did not test to see if the program worked. I wasn't sure if using "unstable" main was a good idea.

I used the "purge" and "autoremove" commands to try and start over because I felt I had muddied the waters by trying a couple different methods. It removed some things but not all, as seen below.

I went into my terminal and did

sudo apt list

And located the "protonvpn" items. (I also have Proton Mail/Calendar installed, so I ignored the Proton items that didn't have "vpn"). This is the list that I received.

proton-vpn-cli/unknown 0.1.6 all
proton-vpn-daemon/unknown 0.13.5 all
proton-vpn-gnome-desktop/unknown 0.10.1 all
proton-vpn-gtk-app/unknown 4.14.1 all
protontricks/noble,noble 1.10.5-1 all
protonvpn-beta-release/unknown 1.0.8 all
protonvpn-cli/unknown 3.13.0-1 all
protonvpn-gui/unknown 1.12.0-1 all
protonvpn/unknown 1.1.0-1 all

(I assume protontricks has nothing to do with any of these, but I included it because it was in the middle of the list, just in case).

First question: What is /unknown? Is that due to the purge and autoremove?

Second question/s: Is it necessary to get rid of these items?

Third question: Is it safe to use an "unstable" version for ProtonVPN? ProtonVPN doesn't offer "official" support for Linux Mint (per their website), so I am trying to figure out the best way to install it.

Thank you everyone for your time and patience. I am very new to Linux and so I am learning as I go.

Hopefully you can help me with this issue so I can get back to using Linux. First of all I'll give you my specs on my PC

• ASUS Tuf Gaming B550-Plus Motherboard

• 5800X

• no32gig ram

• Asus Tuf 6700XT OC

• Viewsonic 32in that has a refresh rate 144hz and my small secondary monitor is 60hz

• Ubuntu 24.04 & Windows 11 both on their own drives

• AMD and Mesa drivers are installed and updated.

I get so I get green, pink and grey blocks all over my main screen then a hard freeze in Ubuntu. While on the secondary monitor, it just freezes. Here is a list of what I tried to do, but to no avail.

• Increasing the wattage on the GPU

• Switched to performance mode in settings

• Switched to performance mode in the UEFI of my motherboard

• Switched to performance mode in CORECtrl

• Switching from HDMI to display port cable.

• Switching ports on the back of the card.

• Using one monitor at a time.

• Switched to an older kernel (6.8)

• Switched from Wayland to Xorg

I dual boot with Windows and while I'm on that OS the card and the rest of the system is stable. I also tested and played Cyberpunk 2077 in Ubuntu and played for a few hours, and the system never froze and played like a dream. Right now I'm stuck and frustrated. I don't know what to do now.

so I plan on upgrading to 26.04 once it releases. However, I installed KDE manually because I didn't know what Kubuntu was back then and don't wanna migrate now that I found out.

Will the new update switch me back to Gnome?

Thanks in advance

Edit: Similiar questions don't answer my question of whether or not KDE will be replaced with Gnome once I upgrade.

I am having a challenge with the upgrade to 24.04.

Failed to connect to https://changelogs.ubuntu.com/meta-release-lts.

...is what I get. I have tried many suggestions based on the previous responses, but to no avail.

When I ssh into an Ubuntu 24 server and run the who command, my user (user1) is shown as having two pseudo-terminals (as below).

Why is this?

On Ubuntu 24.04, thunderbird snap ver. 140.7.1esr-1 rev. 976, it is impossible to open any attachments. After reverting to the previous revision available (rev. 959) of the same version, this problem is solved.

When attempting to open a PDF attachment by clicking on it, no action occurs.

When attempting to open other attachment types, such as a TXT file, a pop-up window appears offering the option Open with: System Handler (default). The OK button is grayed out, and selecting Other… in the dropdown menu results in the appearance of a Select Application window with the message No application found for "plain text document" files.

No related errors are logged within the Error Console or in /var/log/syslog. The issue persists even when running Thunderbird in Safe Mode.

As nobody reported such an important issue yet, I guess it is related to the specific configuration of my computer. How to trace this issue?

[Edit] I was able to reproduce this issue on a fresh Ubuntu 24.04.4 installation with this Thunderbird version. I've filled a bug report: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/2141754

I have an Ubuntu server running a Telegram server for bots. Everything has been working correctly until today. I use Ubuntu 24.04.4 LTS (GNU/Linux 6.8.0-100-generic x86_64) When I try to launch the bot, I get the error

org.apache.http.conn.HttpHostConnectException:  
Connect to <External ip>:8081: Connection denied  

I started exploring and found that I couldn't access some ports from the external network. I have a white IP address. At the same time, ssh and mongodb work via an external IP, and everything is fine with them. The Telegram server and Samba are not working, however if you use an internal IP address while on the same network, everything works fine.

Results of sudo netstat -nlp:

And again, it stops working overnight. I didn't change anything.

I have installed Ubuntu 24.04.4 on an old 2010 MacBook, but the Wifi is not showing up.

If I look at "Additional Drivers" it says it is using an alternative driver "Using dkms source for the Broadcom STA Wireless driver from broadcom-sta-dkms (proprietary)"

I looked at the link [Installing Broadcom Wireless Drivers][1].

When I do the command as suggested of lspci -nn -d 14e4:

I get "03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43224 802.11a/b/g/n [14e4:4353] (rev 01)"

I look at the table and it says "Special Case #1".

"Special Case #1" says: "Special Case #1 - Uses bcma and brcmsmac driver combination. Required firmware is installed by default in the package linux-firmware."

I an not an experienced Linux user so I am a bit lost.

I tried to install linux-firmware by running the command "sudo apt install linux-firmware" but Wifi is still not available.

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!

I am trying to share my screen from my laptop (Kubuntu 25.10, but the same issue on 24.04) to two different Miracast receivers: a TV and a dongle. Both receivers are usable from my Android mobile.

I fixed everything and debugged what I could. I can verify that I can establish a working connection using "gnome-network-devices" (which is said to work fine under KDE), but only a black screen is shared. It seems that capturing does not work on the kubuntu system.

I dug deeper and it seems that no pipewire source is created by KWin, apparently because support for that has not been compiled in. Which puzzles me.

Can someone explain to me or point me to information about why this feature has been disabled in Kubuntu? Or where I went wrong, what I might miss, what I could check?

I see this and if I understand correctly then the pipewire source is missing in there: :

> pactl list sinks short
56      alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI3__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
57      alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI2__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
58      alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI1__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
59      alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__Speaker__sink   PipeWire        s32le 2ch 48000Hz       SUSPENDED

And these deliver nothing :

strings /usr/bin/kwin_wayland | grep -i pipewire
ldd /usr/bin/kwin_wayland | grep pipewire

I get this when debugging the xdg portal:

xdg-desktop-portal-kde: QDBusConnection: couldn't handle call to CreateMonitor, 
no slot matched Could not find slot 
InhibitPortal::CreateMonitor 
No such method 'CreateMonitor' in interface 'org.freedesktop.impl.portal.Inhibit' 

At first I thought this is about a version mismatch, but the versions look fine to me.

I also see this:

codec list not initialized 
No resolution found, falling back to standard FullHD resolution 

which looks strange to me.

I'm using Ubuntu Studio 24.04 LTS (Long Time Support ...)

Since I had problems with the Dolphin filemanager on my NAS drives, I've tried to find a solution. I've got all my media files on NAS (video, audio, photos). To work with it, it is required, to have the media data in columns of the filemanagers details window to be able, to compare it quickly. But this depends from baloo, which is incompatible to network storage (changing inodes and device IDs after each reboot ...).

Posting this at https://bugs.kde.org/show_bug.cgi?id=515574, I had to learn, that Ubuntu 24.04 LTS uses a rather outdated version of Dolphin:

Hi, I'm afraid Dolphin 23.08.5 no longer receives updates or maintenance from KDE; active versions are 25.08.3 or newer. Please upgrade to an active version as soon as your distribution makes it available to you, or use other application distribution methods such as Flathub. Dolphin is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need support for Dolphin 23.08.5, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.

The official repositories are containing no newer versions than 23.08.5.

Actual is 25.12.2

How can I update?

As an alternative, I've tried to install nemo (Cinnamon filemanager). It works well, but the nemo-media-columns are missing for ubuntu noble. Installing it manually does not work and let nemo crashing.

Since I upgraded to 6.8.0-1047, I’ve been experiencing persistent networking issues. Sometimes it works, sometimes it doesn’t, and it’s getting really frustrating. What’s the best way to fix this, or how can I downgrade to an earlier version?

A bit concerned with an update on lubuntu, unsure what to do here. I just ran sudo apt update && sudo apt upgrade -y and I had issues when updating the kernel. Unrelated to the i386 thing. I ran it again and i got this:

tildah@leenux:~$ 

idk what i can do, and my error seems different than other research i've just done, what can I do to remedy this? Is it safe for me to turn off my computer?

I wouldn't post here if I didn't feel like I'm struggling with something basic that I'm missing.

I recently installed a new Ubuntu installation. It was originally installed as Ubuntu Server (25.10), due to the desire to install in RAID, and then Ubuntu desktop (apt install ubuntu-desktop) immediately installed via apt.

It has booted fine, but I've had problems with the hardware crashing. I got rid of an NVIDIA card and crashed went from daily to less than weekly, so I guess that's an improvement.

The problem is that I can't boot the system, but it looks like everything is going fine. It is booting without the splash screen, and everything has a green [ OK ], but then it just stops and gets stuck. This is before networking is working, no GUI and no terminals running on tty2,3,4,5. I can switch to those ttys, but there is just a blinking cursor. Without networking, of course, no SSH.

If I boot into recovery mode, networking works right away, and if I "continue boot" it goes into the desktop, and networking, ssh, etc. are working, but only at 1024x768 resolution and SSH won't connect to a terminal because it isn't "fully booted" and kicks me off.

I've run fsck on all of the filesystems and, although the array that gets mounted as /home has some issues with tree depth or something, they didn't seem like hard errors and correcting them didn't fix it.

For reference, this is where I end up stuck at a black screen with the following boot messages:

The system responds to Ctrl-Alt-Del and reboots cleanly, as well as REISUB reboot. It just won't load the environment completely. It seems like it thinks it's done.

Logs don't seem to contain any issues. I've disabled the wait for network service, for now, since that seemed to be hanging, if that is a clue. Where should I be looking?

I don't understand exactly what difference bitween this two records.

It seems no difference because version of gcc and os version is the same

Host system is legacy BIOS with secure boot disabled. Guest system is W10 legacy boot. When I start the W10 guest, I get the error message below, and all the fixes I can find assume the host is UEFI. All worked OK before the upgrade from 25.04. Any ideas, please?

Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please reinstall virtualbox-dkms package and load the kernel module by executing
'modprobe vboxdrv'
as root.
If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.*

Sorry for lack of info - I am not sure what is relevant.

VB is v7.2.2 installed with apt. (AMD motherboard)

I have tried removing and installing virtualbox-dkms with reboots.

modprobe: ERROR: could not insert 'vboxdrv': Unknown symbol in module, or unknown parameter (see dmesg)

dmesg: vboxdrv: Unknown symbol kvm_enable_virtualization (err -2) after a long list of kvm_amd: Unknown symbol errors.

Blacklisting as suggested as suggested makes no difference, except dmesg errors are not there.

I have removed and re-installed virtualbox-dkms - no difference.

lsmod | grep vboxdrv returns to prompt.

sudo modprobe vboxdrv ; sudo dmesg | tail gives:

Thanks for the replies, and for the tidy-up.

It looks as if I will just have to wait for VirtualBox to be updated, so I have copied the VM folder to an old laptop running 25.04 as a workaround.

I'm experiencing an issue with my integrated Bluetooth adapter (MediaTek MT7921) on my Lenovo ThinkBook (ThinkBook 15 G4 AMD). Until recently it was working fine. I was running 6.11.0-26-generic when I started experiencing the problem, based on online recommendation I have switched to 6.8.0-60-generic. I'm running Ubuntu 24.04.2 LTS. Below I am providing some of the diagnostics that I have run-

Too fast scroll speed using Touchpad 2-finger scroll ONLY in QEMU virtual Ubuntu 24.04.

On Dell Vostro 16 5630 laptop:
two systems:

1. host (Ubuntu 24.04, libinput --version 1.25.0)
2. QEMU virtual (Ubuntu 24.04, libinput --version 1.25.0).

Two scroll devices:

1. Touchpad 2-finger scroll
2. Bluetooth Asus mouse wheel scroll.

Scroll speed test summary:

Host Ubuntu:

touchpad 2-finger scroll - good
mouse wheel scroll - good

QEMU virtual Ubuntu:

touchpad 2-finger scroll - too fast (too fast also using sudo libinput debug-gui)
mouse wheel scroll - good

Host Ubuntu 24.04.2 LTS (works as expected on host system via two finger scroll on touchpad):

$ echo $XDG_SESSION_TYPE

x11

$ xinput list

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
<...>
⎜   ↳ VEN_27C6:00 27C6:0D45 Touchpad            id=10   [slave  pointer  (2)]

$ xinput list-props 10

<...>
    libinput Scrolling Pixel Distance (377):    15
    libinput Scrolling Pixel Distance Default (378):    15
<...>

QEMU Ubuntu 24.04.2 LTS (PROBLEM too fast scroll with two finger scroll via touchpad, but works the same as in the host if using the bluetooth Asus mouse scroll):

$ echo $XDG_SESSION_TYPE

touchpad scroll too fast on both: wayland and x11 (changed to x11 via uncommenting WaylandEnable=false in sudo nano /etc/gdm3/custom.conf and sudo restart)

$ xinput list:

I can select media information entries to display in details view, but the listed columns are empty.

Width, height, duration, or any other information for pictures, sound-files or videos can't be displayed.

How can I get the correct media informations in dolphin?

System information:

Dolphin 21.12.3

Operating System: Ubuntu Studio 22.04
KDE Plasma Version: 5.24.7
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel Version: 5.15.0-70-lowlatency (64-bit)
Graphics Platform: X11
Processors: 16 × 13th Gen Intel® Core™ i7-13700K
Memory: 62.6 GiB of RAM
Graphics Processor: NVIDIA GeForce RTX 3060/PCIe/SSE2

Additional Informations:

• File Search has been disabled in system settings, no index exists. (I've tried with it enabled and full index too ...)
• "kid3" is installed.
• It does not make any difference, wether its on a NTFS, ext4, FAT32, smb or any other file system.

Dolphin shows:

A view to the information panel on the right side shows the correct data. So the information is available for dolphin.

Just to clarify the question, wether indexing has to be enabled, or not:

With indexing enabled (including content):

On my system, Dolphin does NOT show Width and Duration in its columns, but still in the preview. The display according to the first picture above has not been changed.

The pictures show also, that the path for the displayed movies and images are within the indexed path.

There must be some other settings or configurations, to get it working, but out-of-the-box it does not work on Ubundu Studio 22.04 LTS.

Setup:

• Ubuntu 22.04, clean install.
• Dell G15 5521 Laptop
• Latest firmware
• 6.0.8-060008-generic
• Nvidia 525.60.11
• X11 Ubuntu flavour of Gnome

Very randomly and very infrequently (probably once a day for me) a key appears to get stuck and auto-repeats. Pressing any other key stops the auto repeat.

This happens with the default kernel and with 6.0.8.

The problem does not occur on Windows 11. The problem does not occur when running the pre-post keyboard tests (fn key held down when powering on).

The problem occurs on multiple G15 laptops. I have one for work, one for personal use and work has 3 more. All exhibit the same random infrequent problem, but frequently enough to be complained at...

The problem does not always occur when the system is under load. Typing speed does not appear to have any influence on the issue.

dmesg does not show any thing related to keyboard or USB when the issue occurs.

I do not want to turn off key repeat (xset -r).

Is there anything I can try to narrow down where this problem is occurring?

I have looked at numerous different posts and questions but the advice is limited.

Edit 20 September 2023

We now have 8 of the Dell G15's, all up to date. All have the same issue.

The problem does not occur when running Windows.

I was trying to install wordpress on ubuntu using the link and struck at https://ubuntu.com/tutorials/install-and-configure-wordpress#4-configure-database

When I run this command,I get the error-

    -> IDENTIFIED BY 'root';


ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'root'' at line 1

I tried almost every syntax by changing the wordpress@localhost to 'wordpress'@'localhost'

I tried removing and adding the APOSTROPHE on 'root' in IDENTIFIED BY 'root',

then after searching I tried this command as well - GRANT ALL PRIVILEGES ON *.* TO 'wordpress'@'localhost' IDENTIFIED BY 'root' and got

Error - ERROR 1410 (42000): You are not allowed to create a user with GRANT

Nothing found working for me. Please help where am doing mistake. Thanks

Would have thought that connecting Headphones is some basic stuff that should create no complications on an operating system in the year 2020. Not so on Ubuntu....

I followed this article Pair Bose QuietComfort 35 with Ubuntu over Bluetooth with no success.

Here are my steps,that I am taking:

• Putting Headphones in pairing mode
• Open System Settings Bluetooth

Device List says: Unknown Not Set Up

There is no option to click anything whatsoever.

Through another article I found an instruction on how to install a bluetooth manager called Blueman. In the installed software it shows up as "Bluetooth Manager" so these are the steps I am trying with this guy:

• Remove all the entries that are showing up there. I have no idea why there 5 or so of them.
• Turn Headphones off
• Click on search (this makes sure that I know which one I will have to connect to. Since Ubuntu can not tell me the name of the device, it just shows a nasty long number)
• No entries in the list (where the heck did the last 5 come from?! anyway)
• Turn on Headphones and put them into connection mode
• Click on search
• it shows a device with a nasty long number
• right click, connect
• Connection Failed: Software caused connection abort

So do I really have to go back to Windows just because my Bluetooth is not working?!

Image of failed pairing

Update Nov 14: Wow, after I don't know how many hours, suddenly I was able to connect.

My first Bluetooth Device on Ubuntu

I didn't change anything, other than fiddling around with this article: (Maybe that did change a lot under the hood, I am just a Greenhorn) https://wiki.archlinux.org/index.php/Bluetooth_headset#Tested_headsets

Unfortunately the Ubuntu Bluetooth Saga isn't over at this point.

I have no sound on my Headphones! And as you can see in the screenshot, trying to reconnect the device just fails. And, the Headphones never gave me any confirmation signal that it actually did connect.

So the Saga continues, and hours of human life span goes into such important task as to connect a headphone with their computer. I mean, it's just 2020.

Update Nov 20 My BeatsPill+ also does not connect to Ubuntu. I have now 3 Bluetooth devices that won't connect to Ubuntu, but do perfectly so on another Laptop with Windows, on this very Laptop when Windows is running, on two different IPhones, and I would almost bet on any other device except the brand new Ubuntu that I just installed recently. Very bad.

I really enjoy the i3 windows manager (https://i3wm.org/) as it takes out the pain of managing window locations manually.

However as i3 is only a window manager but not a desktop environment, it lacks some functions such as easy support for connecting a second display or changing the sound volume.

How can I set up i3 with a decent desktop environment, so get the best of both worlds?

I've just installed ubuntu 18.4 on my server. As we are behind a firewall so I need a proxy. Linux and my company's proxy do not work together, therefore I've installed cntlm on one computer. This service has a proper authentification on our companies proxy. Then I tried to get this cntlm-proxy from my server.

Let's say User= MyUser, Password = MyPassword, Domain is MyDomain. 172.24.213.55 is the comuter with cntlm service.

In bash.bashrc I've added following lines:

    #set proxy
function setproxy(){
export {http,https,ftp}_proxy="http://MyDomain\\MyUser:MyPassword@172.24.213.55:3128/"

 }

#unset proxy
function unsetproxy() {
unset {http,https,ftp}_proxy
}

I reboot and then run setproxy. But when I then run sudo apt-get update,

I get

407 Proxy Authentification Required [IP: 172.24.213.55 3128].

As a newbe, I cannot find the reason. I changed /etc/profile, /etc/environment, /etc/apt/apt.conf (here with acquire::http::proxy), 95proxies and so on.

Any ideas?

I did some digging around and found that the automatic clean-up for kernels is in /etc/kernel/postinst.d/apt-auto-removal and the file states:

# In the common case this results in two kernels saved (booted into the
# second-latest kernel, we install the latest kernel in an upgrade), but
# can save up to four. Kernel refers here to a distinct release, which can
# potentially be installed in multiple flavours counting as one kernel.

but that script is way above my head and I cannot easily find how autoclean anything but the last 4 kernels.

I'm a complete beginner here. I have installed Xubuntu in VMware Player on my laptop. I can connect to the internet fine on Windows, but not in Xubuntu. I have been trying to follow this guide in the Xubuntu Offline Documentation. The network icon allows me to check "enable networking", but there is no "enable wireless" coming up at all. I followed the "check if the device is recognized" and got this output:

It doesn't say enabled, disabled, claimed or unclaimed anywhere.

I also attempted the "checking for connection to the router" section and got:

eth0 no wireless extensions.

Do you have any advice?

I want to create a Public folder that has full RW access. The problem with my configuration is that Windows users have no issues as guests (they can RW and Delete), my Ubuntu client can't do the same. We can only write and read, but not create or delete.

Here is the my smb.conf from my server:

[global]
    workgroup = WORKGROUP
    netbios name = FILESERVER
    server string = TurnKey FileServer

    os level = 20
    security = user
    map to guest = Bad Password
    passdb backend = tdbsam
    null passwords = yes

    admin users = root
    encrypt passwords = true
    obey pam restrictions = yes
    pam password change = yes
    unix password sync = yes
    passwd program = /usr/bin/passwd %u
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

    add user script = /usr/sbin/useradd -m '%u' -g users -G users
    delete user script = /usr/sbin/userdel -r '%u'
    add group script = /usr/sbin/groupadd '%g'
    delete group script = /usr/sbin/groupdel '%g'
    add user to group script = /usr/sbin/usermod -G '%g' '%u'

    guest account = nobody

    syslog = 0
    log file = /var/log/samba/samba.log
    max log size = 1000

    wins support = yes
    dns proxy = no

    socket options = TCP_NODELAY
    panic action = /usr/share/samba/panic-action %d


[homes]
    comment = Home Directory
    browseable = no
    read only = no
    valid users = %S

    create mask = 0777
    directory mask = 0777
    browseable = yes
    comment = Public Share
    writeable = yes
    public = yes
    path = /srv/storage

The following FSTAB entry doesn't yield full R/W access to the share.

//192.168.0.5/storage /media/myname/TK-Public/ cifs rw 0 0

This doesn't work either

//192.168.0.5/storage /media/myname/TK-Public/ cifs rw,guest,iocharset=utf8,file_mode=0777,dir_mode=0777,noperm 0 0

Using the following location in Nemo/Nautilus w/o the Share being mounted does work:

smb://192.168.0.5/storage/

Extra info. I just noticed that if I copy a file to the share after mounting, my Ubuntu client immediately make "nobody" be the owner, and the group "no group" has read and write, with everyone else as read-only.

What am I doing wrong?

I've been reading docs and various pages for a few hours now and can't seem to put all of the pieces together on this. Basically I am trying to get 12.04 installed on my MBP 8,2 with graphics card switching working in some way or another. My basic understanding is that I need to do an EFI boot install of ubuntu so that graphics card switching will work (due to the hardware design). From there I may be able to use one of the kernel modules for graphics switching:

https://help.ubuntu.com/community/HybridGraphics

That article isn't clear on whether I need to do an EFI install. I have also seen comments in posts here that say and EFI install works by default as long as you have refit installed. Overall, I'm quite lost as to the simplest way to proceed to get an install up and running with graphics switching. I don't mind using open source GFX drivers as long as the basics work.

Any help towards a solution is greatly appreciated.

I would like to modify the pitch of my audio output.

I know you can use software such as PlayItSlowly to listen to an audio file and alter the pitch in the process, but what I am looking for is a way to modify the pitch just as I do with the volume.

I can do it on Windows with Realtek's sound manager, so I guess there must be a way to do it on Linux as well.
