I have one instance of Microcloud setup on my LAN network, and cant find any real documentation regarding how to set it up across WAN. Any help would be appreciated.

Secure boot. What is the - HP UEFI secure boot 2013 DB key - used for?

My current understanding it does the same thing (but expires 2033) as the Microsoft UEFI CA 2023 ie, Signs third-party boot loaders and EFI applications. In other words will it allow Ubuntu to boot in secure boot mode? (Assuming other keys are correct, of course.)

My mouse pointer now has an offset in certain situations, in KDE (Kubuntu). The pointer seems to work properly in menus, but not in text editors (like kate).

I have the following situation:

and need to resize my /boot partition at the very beginning of the drive. Now, unfortunately for some poor design when I installed Ubuntu I set my EFI partition in between the /boot and the root partition (/) of roughly 1TB.

My goal would be to shrink the / for ~650MB to add to the /boot; however, it appears this would necessarily pass through the EFI – which is something I'm aware should not be touched...

So, my question is it safe to do it or I should leave things as they are? I'm asking since I haven't allocated enough space for multiple updates at the same time, and I'm always forced to promptly removed unsed headers in order to update/upgrade the system. Thanks in advance!

Trying to use Thunderbird email system for several emails addresses. The Godaddy/Microsoft combination gives an error 12 when set up. The setup was done multiple times (adding and deleting the account, deleting passwords, etc.) trying many things. The data is

Incoming Imap outlook.office365.con 993 SSL/TLS OAuth2

Outgoing SMTP.office365.com 587 Starttls Oauth2

The account sets up and is confirmed but will not pass any data. Getting an error 12.
Godaddy is no help.

Gmail and yahoo accounts work great but not Godaddy. Any ideas??

I use three PCs:

1. A desktop PC running Ubuntu 25.10, using Wayland.

2. A laptop running Ubuntu 24.04.

3. A laptop running Windows 11.

I want to use Remote Desktop to connect to the PC 1 (the desktop running Ubuntu 25.10).

I use this KVM switch to switch my 24-inch screen between the three computers.

What I want to do is to have my big monitor screen attach to one of the laptops (PCs 2 or 3), and then connect from there to PC 1 using Remote Desktop.

My problem is that I can't connect using Remote Desktop to PC 1 unless the big monitor is connected to it. When I set the KVM switch to one of the laptops, there is no screen connected to the desktop (PC 1) and it doesn't allow RDP connections when that happens. It disconnects me as soon as I enter my credentials. Or if I'm using an existing RDP connection to the PC while it's displaying on the screen, it disconnects as soon as I switch my screen to another computer. Is there a setting to allow RDP connections without the screen attached?

Note: Not a duplicate of "Ubuntu 22.04 remote desktop headless?". That question is about connecting without having to login first. That's not my problem at all; I'm happy, if necessary, to login first and then connect remotely. My issue is how to connect when a screen is not connected to the PC, which the other question doesn't cover.

Update: I've tried user68186's suggestions. I restarted the PC while connected to the screen, logged in, then pressed the button on the KVM to connect to a laptop, and tried remote desktop to the PC. Same results: refused to connect. Unfortunately, I cannot use X11 because, since Ubuntu 25.10, the new version of GNOME only supports Wayland.

I can't use a dummy HDMI plug because the HDMI port is already used up as it's connected to the KVM switch.

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 am 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 ended up with the following output/errors:

I have a problem with bluetooth on my laptop Lenovo R7000P with processor AMD 8945HX and Ubuntu 24.04.3 LTS.

I can't use Bluetooth, it doesn't work. When I try to turn on Bluetooth the button is greyed out.

I searched, and in the end, DeepSeek advice helped me: It wrote the following list of commands, which restarts the driver and really helps.

sudo modprobe -r btusb  
sleep 2  
sudo modprobe btusb  
sudo systemctl restart bluetooth

But these commands need to be executed every time I restart the computer. I can automate this so that the file runs itself every time, but I don't like it, I want to fix the problem. I have dual-boot with Windows, and Bluetooth is running on Windows. P.S. so, i turned off fast startup in windows 11. It didnt help me.

All drivers and system are updated...

I recently cleared my laptop of Windows and installed Ubuntu Budgie 24.04.3 LTS. It is a 2018 Razer Blade 15 Adv. I have two problems.

1. I installed OpenRazer, which also includes enrolling a MOK. It seems to randomly forget the MOK. It cannot load OpenRazer until I re-enroll the MOK again. Is there something that would remove the MOK automatically?

2. Sometimes the system will lock up tight and I have to force reboot. The special key (PrtSc) to talk directly to the kernel doesn't work to reboot. I have to force power off. The special key works when not frozen. Also with this comes the MOK being removed from the boot and OpenRazer not loading. Where would I look to figure out what is causing these lock ups? I have checked the logs, but nothing jumps out.

I am facing an audio issue on Lenovo ThinkPad E14 Gen 7 (Intel) running Ubuntu 24.04.

When I plug in wired headphones Ubuntu detects them correctly, but no sound is heard through the headphones. Audio either continues playing through the laptop speakers or becomes silent.

This appears to be a jack routing / Realtek audio issue.

System information:

• Laptop: Lenovo ThinkPad E14 Gen 7 (Intel)
• CPU: Intel
• Audio: Intel HDA + Realtek codec
• OS: Ubuntu 24.04 LTS (fresh + fully updated)
• Audio stack: PipeWire (default)

I recently installed Ubuntu on an Acer Chromebook 14 CB3-431 laptop. It appears the installation did not recognize my touchpad. Is there a fix to the problem? Thanks

I have ubuntu 25.04. I installed steam the recommended way (via the deb package on their website).

When I open steam from gnome (clicking the icon) the window of steam fails to open and it's blinking in the app bar...

But there's no issue if I run it from the terminal. (by typing just steam)

Why?

I tried using xrandr command to lower resolution, run wine some_game.exe, then return resolution to normal. like so:

xrandr --size 1024x768 --output DP-0 --scale 1x1
WINEARCH=win32 wine Hoyle_Board_Games.exe
xrandr --size 3840x2160 --output DP-0 --scale 0.66x0.66

but it is not behaving as expected.

Running the last command makes everything huge,

but when I run xrandr --size 3840x2160 --output DP-0 --scale 2x2 everything becomes very tiny.

I have NVidia drivers installed. I don't know if this is caused by compounded scaling from NVIDIA X Server Settings, but what I want is that my screen resolution and scaling returns to default display settings.

I have a brand-new gaming laptop with an RTX 4060, which I installed Ubuntu 22.04 on yesterday. Upon logging in and changing the graphics driver from Nouveau to Nvidia proprietary, I encountered consistent graphical glitches after a few minutes of usage. They look like this:

The glitchy regions flicker and change when moving my mouse, alt-tabbing, etc. Eventually they get more visually drastic, making the computer unusable. Sometimes it even hangs.

I tried reinstalling - no luck. Changing the display manager from Xorg to Wayland seemed to help, but the glitches still occurred after about 30 minutes of usage.

Interestingly, I attempted to screenshot the glitchy portions while on Xorg, and they showed up as all white in the image (despite looking very different on the screen itself).

This problem does not seem to occur in Windows, which by default uses the integrated graphics to render the desktop. This points to it being an Nvidia-related issue. I have verified that the issue occurs on Nvidia driver versions 525 and 530.

Note that I have not tested whether this issue occurs with Nouveau.

I did not encounter this issue when using 22.04 on my previous laptop, which had a GeForce MX250.

I installed VMWare Workstation pro 17.0.0 (build-20800274) on Ubuntu 22.04 (5.19.0-38-generic). However, I can't access the internet from the guest machine. I searched the internet and tried some resolutions (e.g. https://communities.vmware.com/t5/VMware-Workstation-Pro/Virtual-ethernet-failed/td-p/2906720). But they don't seem to work. For example, I tried to install some patch and compile modules.

git clone https://github.com/mkubecek/vmware-host-modules
git checkout workstation-17.0.0
sudo make
sudo make install

Then I compile the modules.

sudo vmware-modconfig --console --install-all  

However, I got the following messages.

So far I've tried to run this command by downgrading curl to 7.33, upgrading to 7.68 and even reinstalled my OS and tried this command but its always shows me same error. I've been scratching my head to solve this problem for last 2 night any suggestion or solution would be much appreciated.

This applies to Nautilus, Gedit, and others. I would like to select, for example, Copy and Paste from a drop down menu, but I am forced to use either the right-click menu or Ctrl-C Ctrl-V shortcuts, because the drop-down menus are non-existent. These menus provided easy access for many essential functions, and I would like to use them on Ubuntu 18.04.

This image (from Ubuntu 16.04) shows the drop-menu feature I'm looking for.

I know there are similar questions about this issue, but the answers are not definitive and recommend installing Gnome Global Application Menu, which does not implement this feature properly. Also, there are rumors that this shell extension is no longer supported. In either case, it doesn't work.

I've tried several settings, installed Gnome Tweak Tool, logged in with Unity User interface, but nothing works. It doesn't matter if the menus are located in the window's title bar or the top menu bar, as long as they are available somewhere.

My question is: Is it even possible to have these drop-down menus, or should I just give up and stop wasting my time?

I'm new to ubuntu. While installing the node.js package, it recommended to run sudo apt-get -f install but when I run the command I got some errors about dependency problems

Can someone help me regarding this problem?

I had recently installed Ubuntu on my Sager Notebook Computer , and I noticed after a while that there was a LOT of screen tearing on my PC. I started researching the topic and found a lot of solutions. The first thing I tried was installing nvidia drivers using

sudo apt-get install nvidia-current

This did not fix my problem.

I then tried to change the settings in Nvidia X Server Settings, but it said that "PRIME Displays cannot be controlled by nvidia-settings and must be configured by an external RandR capable tool. The display is shown in the layout window for information purposes only."

Nvidia X Server PRIME Display Issue:

I then tried to install CompizConfig and change the refresh rate to >144 Hertz, but that also did not effect anything.

After some more research I tried to use the xrandr command to change the refresh rate, but that also had no effect.

I tried to disable Wayland and enable GDM3, yet that also yielded no change.

I then tried installing Bumblebee in hopes of fixing the sync, but that had no effect, and even Soft-Bricked my computer later.

Here are my specs : http://www.sagernotebook.com/Notebook-NP7870.html

I am running Ubuntu 16.04 on Dell XPS 13 Intel HD Graphics 520 connected to Razer Core through its USB Thunderbolt that has Nvidia GTX1060 for powering a full HD external display. I have installed latest nvidia driver (378.13) from PPA repository and update the system and able to make a mirror displays on my internal and external screen. So I assume the eGPU setup is working well as it ables to run both displays in mirrors mode, but the problem is once I unchecked the Mirror displays to make an extended displays, the display becomes stretched like this:

The left side is my external display and the right side is my internal display. When I click somewhere on desktop area with my mouse, it is not clicking at right location. It seems due to the incorrect resolution, but I can still click properly the sidebar and top bar menu (wireless, time, settings).

I have tried different Nvidia drivers that available to be installed, i.e 367.57, 370.28, and 375.39, but it has made no difference. The configuration in nvidia-settings is set to default. I did not change anything there.

I am adding screenshot for nvidia-settings and Screen Display settings:

In Selection option, there are X screen 0, Anchor Communication, and PRIME Display. I am not sure if my internal display should be listed there, but I can see my internal and external display in Screen Display settings.

I have a problem adding PPTP VPN.

I just upgraded Ubuntu with sudo apt-get upgrade and the PPTP VPN stopped working with this message:

The VPN Connection 'VPN Connection 1' failed because the VPN service failed to start

I recently installed Ubuntu 16.04 x64 in an Asus GL502VM. It comes with a GTX 1060 graphics card. I installed multiple versions of the Nvidia drivers trying to solve the problem, but all of them have the same behavior. Currently it has the 378.09.

It works well until I suspend Ubuntu. After logging in it looks like this:

The Ubuntu UI blinks and has a strange visual behavior when I pass the mouse over it. It doesn't appear on the screenshot.

Changing the tty doesn't solve the problem, and sometimes it gets stuck at a black screen.

If I restart or logout and login again, the problem disappears until the next time I suspend Ubuntu.

I am totally new to Linux, servers and websites. I recently set up Apache2, Python, PHP, and MySQL for setting up a LAMP server. I am using Xubuntu 16.04 and PHP 7.0.11. I followed a guide and placed a PHP file named testing.php in it with:

<?php phpinfo(); ?> 

It doesn't show anything on localhost/testing.php All it shows is the code itself.

I think the overlay scrollbars that come up in menus and the Nautilus file manager work really well, especially with my touchscreen (it doesn't allow gestures, rather bittersweet). I've found ways to disable them, but is there a way to do the opposite? Can I make them so that they always appear, regardless of my mouse position?

Thanks!

I have been enjoying dual monitors using Xubuntu with Nvidia driver 340.58 for some time now. However, suddenly one of the monitors stops working. In nvidia-setting panel it just appears as "Off" and I couldn't change any settings.

Do you have any idea what might be causing the problem?

First my laptop CPU/GPU is Intel Celeron N2815 (Bay Trail) and I am in dual boot with windows 8.

I have upgraded from ubuntu 13.10 to 14.04 today through update manager. And after upgrading and after booting the only thing that happens is that screen doesn't show ubuntu logo for booting and that at some point it turns off. Also then I hear ubuntu sound when it comes to login screen. The screen doesn't turn on after that. (Also I have to tell you that I tried to install ubuntu 14.04 from USB and that there was the same problem. It asked me what I want to do (Try or install ubuntu) and it doesn't matter what option I selected the result was the same.)

Then I decided to try some stuf. First I tried to bootup with Ubuntu with Linux 3.11.0-19-generic. And it went well. The screen was working and everything was fine. Then I decided to try to hook my desktops screen on laptop via HDMI and right away it worked. Both screens were on and I had two screens. So I went in System Settings -> Displays and there saw 3 screens. Built-in Display, my secondary desktop display and unknown display. In 13.10 I had to turn of Unknown Display because all the workspaces were size of built-in display + Unknown Display so I didn't saw my edges.

Now that I know that my graphics drivers work and everything is fine, I tried default booting in ubuntu. Still connected to my desktop display via HDMI it started booting and booted. But the problem was that only desktops display was working. Laptops display was off. So happily I again went into Display settings only to notice that I only get two displays. Desktops and some other with strange unfamiliar name: Chi Mei Optoelectronics corp. 15,6" (I will add screen shots :) ). This other screen was on and should somewhere work but not on laptop. As far as I can remember Laptops screen was always named Built-in Display (in 12.04 and 13.10). And I never had the same problem.

So now I have some questions. What is the difference between: Ubuntu with Linux 3.11.0-19-generic and 3.13.0-24-generic (I don't know much about Linux as I am new to this stuff. But I know a thing or two about computers.)? Is this different kernels? Also I want to know if there is important difference between and if it is important which one I use to run ubuntu. Of cours I want to use default one as I don't want to wait every time to ask me. And of course I would be very grateful if anyone will take time and try to help me.

Thank you for your time :)

both network card speed is 1000MBPS. How do I check the bond0 network speed.

I noticed that my 11.10 does not hibernate. When I hibernate, and starts PC, it doesn't restore all my open apps etc. Its like a shutdown ... why might that be?

UPDATE

• Output from gsettings http://pastie.org/2926504
• Using a vanilla Ubuntu Desktop 11.10 installed yesterday (no more from alternate CD, but problem still persists)
• I dont see any options in BIOS for S1, S3 or ACPI, are they hidden somewhere? I am using ASUS H67 Evo, I entered the Advanced mode of the BIOS, I still dont see those stuff

I've encountered what I can best describe as "unpredictable" behaviour of the "clipboard". But in its own way, it actually is "predictable"", as it is not an X bug, as such.

It largely results from different X applications using different X features in different ways...

But it doesn't really help to know that it isn't "actually" a bug. because it feels like a bug!

There is a list (below) of what I've found / tested.

Is there some way (a daemon?), which irons out all these wrinkles? I'd prefer something that doesn't sit in the panel.

The X / Ubuntu clipboard is potentially awesome, because of its 2/3 levels ability, but is a bit annoying because of the inconsistent implementations...

I've been trying to understand why the copy/paste thing didn't always do what I expected... It's amazing what you can learn when you read the info docs :) ... But a question can hit the target faster.

The main issue seems to come about when the source application is shut down, and you try to access "clipboard" data which came from that application.

X GUI applications have two major copy/paste methods (modes).

Mode NAME    Text Copy method         Text Paste  method
----------   ---------------------    -------------------
PRIMARY      currently selected       mouse middle-click
CLIPBOARD    Control+C selection      Control+V

I've tested the behaviour of the selection modes for a few different X applications: gvim, gedit, firefox, and gnome-terminal.

NB: * All pasting was done into gedit * The gedit source was from another (root) instance)
* I've tried a couple of "managers", parcelite and pastie, but I can't see any point in comparing them, because neither address the problem. That is, normally expected copy / paste keyboard actions are "inconsistent"

I have problems transferring binary programs to a micro-controller prototype board when using ubuntu/kubuntu to mount the board via usb. With MacOS and Windows there are no problems. I have found the writing from Ubuntu definitely changes the written file. I suspect that the write caching is the problem. How can I disable it, or what else might be the problem.
