I noticed that 26.04 desktop os is strictly Wayland, the bundled nvidia settings seems to lack a lot of the configurations that once existed on previous version of Ubuntu via XOrg11.

• Is there any way to get these configuratble menus, or add these settings back in manuall via key/value profile?

• Is there a way to upgrade to drivers version 610 for nvidia instead of 595 (according to nvidia website this is available but ubuntu-drivers maximum is 595), any way to upgrade?

• I heard LInux Kernel 7.10 is available any way to upgrade to this as well?

Any attempts to upgrade Nvidia drivers via .run download will essentially bricked the os, either stuck with login loop, or drivers completely not loaded resulting in single screen display,

Thanks!

I have 2 servers that I access remotely (even the BIOS) One is an AMD Ryzen and the other is an Intel Xeon. I installed Ubuntu 24 AMD version on both. I didn't have any trouble with the Xeon until I tried to update. I got in through grub and saved the critical files to the other server. I would like to reload Ubuntu for Xeon remotely without a USB. If my only option is a USB then I would have to make a 200 mile round trip.

I have Kubuntu 24.04 installed on my desktop that has an Nvidia graphics card. After attempting to resolve issues with my second monitor not being recognized, I restarted for driver changes and now I'm unable to boot into Kubuntu at all.

I have tried adjusting quiet splash to nomodeset on all available kernels and recovery mode kernels in grub. I was able to see the boot process hang on the last line in the boot process, but I'm not quite certain what that means the issue is. To clarify, none of the kernel boot options in grub work, and they all stop at the same point.

I can boot from a live CD working. The safe graphics option and change the grub file contents of the install where it's located on my drive. This was recommended based on some preliminary troubleshooting searching the web.

After that I'm not entirely certain what to do instead of completely reinstalling, which I am hesitant to do since I just got everything set up and working.

I will admit, I am not entirely familiar with how to update the grub file after changing it, or if that even is part of my issue. I've just made the switch from Windows in the last year and am not the most literate at this stuff, so I apologize in advance if I ask any follow-up questions that might be a bit silly.

I have an old notebook i use to basically mess around with, sorta like a 'frankenstein' machine; many parts missing but still motoring along. I have only Linux OS installed, 3: Ubuntu;deepin 23 and Linux mint. So, right now neither the built-in keyboard nor the external one works at boot/grub (already tried others) which means I can only boot into the last one in memory (Thanks to an addition to /etc/default/grub: GRUB_SAVEDEFAULT=true)DeepinOS 23. which is not really the best of their distros.
I would like to upgrade to 25 but, it's not possible, since 25 only allows a clean installation via ISO image and my aforementioned handicaps prevent me from booting from USB. I did some research through AI and found out that there's a possibility with the 'GRUB Loopback Boot'. does anyone on this forum have any experience with such a procedure?

I'm on Ubuntu 25.10 with default everything. Until I tried xfce (briefly) then switched back.

Since then I can't run Inkscape. When I run it from the terminal I get

$ inkscape

I think xfce might have reset the cursor theme, or I might even have done it myself, I don't recall.

But using Tweaks I've set the cursor theme to Yaru.

That theme isn't listed when I run

$ sudo update-alternatives --config x-cursor-theme
There are 7 choices for the alternative x-cursor-theme (providing /usr/share/icons/default/index.theme).

But /usr/share/icons/Yaru/cursor.theme does exist.

I have also tried running

$ dconf reset /org/gnome/desktop/interface/cursor-theme

but no luck.

Following this question I checked and these files exist:

/usr/share/icons/Yaru/cursors/default
/usr/share/icons/Yaru/cursors/left_ptr

Any ideas what's wrong, and how I can get Inkscape running again?

I have a Lenovo ThinkPad P14s with an NVIDIA T550 GPU, and after a few minutes or even seconds after starting Ubuntu, the system freezes. Sometimes I can switch to text mode with Ctrl + Alt + F3, but I haven’t been able to find what is causing the issue. I have tried isolating the graphics cards and testing different configurations, but the problem continues. This usually happens after restarting the laptop. If I turn on the computer after not using it for a long time, everything works fine. However, after running sudo reboot -i, Ubuntu freezes again. Could this be related to temperature readings or thermal issues after the system starts?

After using for a period, Chrome sometimes becomes very slow and eventually freezes. Sometimes I can restart Chrome, other times I have to reboot my laptop. System Monitor shows multiple errors even before slowdown, mostly of the form '/opt/google/chrome/chrome -type-renderer --crashpad-handler-pid-4808-enable-crash-reporter-.... followed by another 10 lines of alpha-numeric words and numbers. Any suggestions on how to find out what is causing the problem and possible cure?

I'm trying to install the Fender Studio Pro 8.1 beta for Linux.

The problem is that is either comes as a flatpack (which I understand can't access the host system, which means all my third-party VST's can't be used), or as a .deb package.

I try to install the .deb package, but it have dependencies on old FFMPEG libraries, like for example libavcodec60, which aren't available in 26.04.

I've found a few .deb files for the dependencies, but they in turn have other old dependencies, leading to a never ending rabbit hole and a possibly broken system.

Is there a way to either install the old dependencies (without breaking my system), or to bypass their need in a way that won't nag me about "broken" packages and the use of apt --fix-broken install?

The list of unmet dependencies:

Unsatisfied dependencies:
 studiopro8 : Depends: libavcodec60 (>= 7:6.0) but it is not installable
              Depends: libavformat60 (>= 7:6.0) but it is not installable
              Depends: libavutil58 (>= 7:6.0) but it is not installable
              Depends: libsdbus-c++1 (>= 1.4.0) but it is not installable
              Depends: libswscale7 (>= 7:6.0) but it is not installable

Have searched and found conflicting info..

Can Gnome on 26.04 run as an X11 session?

Or do I have to install/run XFCE or similar?

Mainly need this to run NoMachine on a headless server.

Thanks.

This subject has been around for a while but I think it needs an update. I have experienced the issue several times before and I have always been able to fix it by reinstalling the driver. However with a recent system update, no such luck.

My system is Ubuntu 22.04 with Kernel: 6.8.0-124-generic x86_64 bits, and a dual head graphics card NVIDIA GeForce GT 710. The correct driver is nvidia-driver-470.

The update installed the nvidia driver 535 which doesn't work. Attempts to install the 470 driver using apt install ignores the 470 driver and installs the 535 instead. I understand that this is because the 470 driver is no longer supported even though it is a common piece of hardware and is still available.

I was fortunate to discover after much gnashing of teeth that I could force the system to use a generic driver (Nouveau) by:

sudo apt purge "*nvidia*"

sudo apt autoremove --purge

sudo reboot

Then by going to Additional Drivers I found I could now select nvidia-driver-470 and install. Now things work again!

So my question is what exactly is going on? Also is it going to be safe to install future updates without breaking my system?

I am recently Installed ubuntu os. In that I can't see the wifi symbol i tried all method but result is negative. So i researched many articles shows Your wifi driver may problem change inter wifi thats like

My wifi driver ls MediaTek9702 does this not support wifi in the ubuntu. And also in additional drivers it does not show anything if loads like half hour still no output.

I was using Kubuntu, but the new LTS slowed my computer down so I'm back to an older Ubuntu LTS. I'd like to see the seconds but the same way I was able to do it in Kubuntu, by hovering over the clock, not showing them all the time on the regular clock (because that's supposed to use more computing power) so, does anyone know how to do it? Or at least showing them in the dropdown calendar instead of the top bar?

I am trying to install Lubuntu 26.04 on an old computer, dual boot alongside Windows 10 on the same GPT SSD, however after a successful installation the computer boots into Windows. Grub does not appear, and I have no option to boot into Linux.

The motherboard is a Hybrid EFI Gigabyte 78LMT. Apparently it can make dual booting very tricky, but I lack the technical knowledge to understand details like these.

Specs:

• Motherboard: Gigabyte GA-78LMT-USB3 Rev. 5.0

• CPU: AMD FX-8350 (8-core, 125W, AM3+)

• RAM: 8GB DDR3 1600 MHz (2×4 GB)

• GPU: AMD Radeon HD 7750 1GB GDDR5

I have tried this solution but boot-repair gives the following error:"The current session is in Bios-compatibility mode". I cannot setup the BIOS to boot USB in EFI mode, the option exists for CD/DVD only, as explained here:

Although Gigabyte's Hybrid EFI contains a full-fledged EFI implementation from an OS's perspective, the firmware setup utility provides almost no options to help you use this functionality. Specifically, only one firmware option, entitled "EFI CD/DVD Boot Option," on the "Advanced BIOS Features" menu, relates to this feature.

In another question, someone tried to install from CD, apparently without success. I have no CD/DVD drive to test this option.

I cannot find any UEFI settings to select Ubuntu as the default operating system to boot either; thus, it seems this solution will not work: no UEFI settings.

I can choose from which disk to boot; Windows and Ubuntu are on the same SDD. I have also an old HDD I use for backup attached to the motherboard; perhaps installing GRUB on it could be a solution?

Recently had a friend help me switch from Windows 10 to Ubuntu 24.04.4 LTS.

Found myself struggling while filling out PDFs of scanned paper documents. On Windows, I used the free version of Adobe Acrobat. It has the option to format inserted text letter by letter into evenly spaced boxes, which is something a lot of these documents call for.

I can obviously kind of McGiver a similar result by inserting several spaces after each letter, incredibly clunky though.

Can someone recommend a PDF viewer and editor for Ubuntu that allows inserting text in this format?

I have a Lenovo ThinkPad X9-15 Gen 1 with Ubuntu 26.04 (Resolute Raccoon, kernel 7.0.0-22-generic) and the built-in camera is not working in any application (Firefox, GNOME Camera, etc.). I tried to replicate solutions, given for ubuntu 24, but with no avail.

Some troubleshooting

Ubuntu version: 26.04

Ubuntu sees the camera:

$ v4l2-ctl --list-devices
Intel MIPI Camera (platform:v4l2loopback-000):
    /dev/video0

What I've already tried:

• Installed oem-sutton-dana-meta, libcamhal0, linux-modules-ipu7-generic, v4l2loopback-dkms

• v4l2-ctl --list-devices shows the camera via v4l2loopback

• ipu7x.so is present in /usr/lib/libcamhal/plugins/

• pw-cli list-objects shows the camera in PipeWire

v4l2-relayd -d fails with:

CamHAL[ERR] load_camera_hal_library, failed to open PCI device
gst_parse_launch_full: assertion 'pipeline_description != NULL' failed

libcamhal-ipu7x cannot be installed due to broken dependencies:

Depends: libjsoncpp25 but it is not installable (Ubuntu 26.04 has libjsoncpp26)
Depends: libia-cca-ipu7x0
Depends: libia-log-ipu7x0
Depends: libcamhal-ipu7x-common

After upgrading from Ubuntu 25. to Ubuntu 26.04 LTS, randomly when starting Thunderbird the screen freezes and says "kernel panic fatal exception in interrupt" After restart it continues to work, but randomly crashes again?

Today I upgraded to Kubuntu 26.04.

Moving my mouse coursor onto my second monitor using Wayland (Plasma) will permanently freeze the video output. This also happens in the login screen. I am able to circumvent it by using awesome-wm, but strongly prefer plasma. And it only occures when moving the mouse coursor there, having applications open and using keyboard shortcuts does not trigger it. Disabling the internal screen and just using the external one also does not help.

System is still running, as I am able to ssh in and reboot it.

/var/crash/ is empty prime-select is on nvidia. I should not that I can switch to intel, but that also disables the HDMI port, so the problem cannot be replicated then.

Adding KWIN_FORCE_SW_CURSOR=1 to /etc/environment does not help.

I’m testing Ubuntu 26.04 with Btrfs and noticed that the installer creates a flat Btrfs layout (no @ and @home subvolumes), unlike Kubuntu which sets them up by default.

This causes issues with tools like Timeshift that expect the standard @ layout.

Question:
Is there a supported or recommended way to install Ubuntu 26.04 with Btrfs using @ and @home subvolumes during installation (without manual post-install restructuring)?

Alternatively:

• Is this behavior intentional in Ubuntu’s installer?

• Are there plans to support a proper Btrfs subvolume layout like Kubuntu?

• What is the best practice for users who want snapshot-based rollback (Timeshift/Snapper) on Ubuntu?

Any official guidance or recommended workflow would be appreciated.

For 26.04 I did an almost complete reinstallation of my system, only keeping my home drive but formatting all system drives.

I installed Thunderbird with apt, and it works fine with all my old settings and configurations.

But it doesn't show up in the applications menu... If I press the Windows key on my keyboard, searching for e.g. Vivaldi (my browser of choice) allows me to find and start it just fine, but Thunderbird does not show up. I have to start if from a terminal.

The /usr/share/applications/thunderbird.desktop file is there and seems to be fine.

I've logged out/in and restarted my computer multiple times to no avail.

Was something changed in regards to mail and/or Thunderbird in 26.04? Why can't I search for it?

Addendum: The application doesn't have the Thunderbird icon once I run it. Could possibly be related.

Update 2026-06-21: This now works. I'm not sure what update or other thing I used, but suddenly it works as intended again. Thunderbird is shown as an app in the app menu, and have the correct icon.

As the title says, I just installed 26.04 on my MacBook Pro. WiFi does not work, but it's fixable as shown below:

The question is, why did I have to do so much manual work? This is not user-friendly.

After the fresh install, the WiFi didn't work. Looking at dmesg, I found this:

b43-phy0: Broadcom 4360 WLAN found (core revision 42)
b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 12, Type 11 (AC), Revision 1)
b43 bcma0:1: probe with driver b43 failed with error -95
Broadcom 43xx driver loaded \[ Features: PNL \]

A bit of Googling shows that problems like this have been reported by some users for years.

The ubuntu-drivers devices command suggested in some posts produces no output. (That's a user interface that needs some improvement).

On this MBP, lspci -nn -d 14e4: reports

03:00.0 Network controller \[0280\]: Broadcom Inc. and subsidiaries BCM4360  
802.11ac Dual Band Wireless Network Adapter \[14e4:43a0\] (rev 03)

04:00.0 Multimedia controller \[0480\]: Broadcom Inc. and subsidiaries 720p
FaceTime HD Camera \[14e4:1570\]

Following the suggestions in other posts here I did sudo apt install broadcom-sta-dkms and now sudo apt show broadcom-sta-dkms shows:

Package: broadcom-sta-dkms
Version: 6.30.223.271-29ubuntu1

Now, after rebooting, I found these lines in my dmesg:

wlan0: Broadcom BCM43a0 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)
wl 0000:03:00.0 wlp3s0: renamed from wlan0

And in lspci -k output I find this:

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Dual Band Wireless Network Adapter (rev 03)
    Subsystem: Apple Inc. Device 0134
    Kernel driver in use: wl
    Kernel modules: bcma, wl

Now it works, so it's fixable, but it's way more difficult than it ought to be.

Since I'm having audio issues on both my Ubuntu machines, felt like using my improved techniques to figure out more about what's wrong on the one that at least sometimes works.

So, HDMI via internal graphics that sometimes appears as an Output Device in Sound settings, but sometimes doesn't, causing a Dummy Audio issue, and for all times eventually is fixed as long as I keep resetting until a success.

But I'll rather stop having to repeated reset after a required post-update reset.

So, what I know:

~$ lspci | grep -i audio
06:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Raven/Raven2/Fenghuang HDMI/DP Audio Controller

But that doesn't currently appear in alsamixer but it did when I checked during a time it did work.

And aplay -l is empty:

My friend is trying to install Ubuntu 24.04 on a new Acer desktop (very recent).

Booting from the USB drive works fine, any application or command works.

However the SSD drive is not detected anywhere: not by GParted, not by df, not by fdisk, and not by the Ubuntu installer.

For instance, sudo fdisk /dev/sda gives an error:

fdisk: cannot open /dev/sda: Invalid argument

The SSD drive works fine, since MS Windows is installed on it (as usual) and it works normally.

We tried to disable "secure boot" in the BIOS in case this is the cause, but no luck. [edit] We put secure boot back on, following comments.

2. RAID has been turned off in the BIOS (Acer support also said to do this), but it still doesn't work.

3. @oldfred: This is the output of the commands that you proposed. I'm not sure how to interpret it.

When using the native print dialog in chromium (installed via snap) in Ubuntu 21.04, I get problems: it takes a long time to render, makes me unable to choose a page range (until the rendering is complete), and seems not to be able to work if not installed with extra permissions (with snap install --devmode chromium) (apparmor disables the access to the ppd file as can be seen from journalctl).

How do I make it use the system print dialog? (Always, no matter how it is invoked: from shell or from the menu/icon.)

I can't install ncurses library on my computer. When I compile it with make , I get a fatal error n.curses.h: No such file or directory.

I tried to install it via terminal, however I didn't succeed. I've got this response: sudo apt-get install libncurses5 libncurses5:i386

I also tried to fix my source.list since I used: sudo tee /etc/apt/sources.list

However, it deleted everything on the file. Searching on web I found this:

(...)

Copied and pasted on my source.list and placed '#' where it says deb or deb-src. Now, I can't download any software via terminal, can you help me?

LibreOffice does not seem to have an inbuilt voice type feature. Is there any way to enable voice typing in LibreOffice?

If not, is there any other free and open source software with which I can voice type in LibreOffice?

I am using Ubuntu 24.04.

I have Ubuntu 18.04 Dual booting with Windows 10 on my HP-EliteBook-745-G2, and for some reason, I cannot seem to find WiFi networks through my WiFi adapter, but Ethernet works (however, Ethernet stops working properly if I shut my screen down, and go back into my laptop, forcing me to restart my laptop to use Ethernet).

What I have done that didn't work:

• Uninstalled Kernels and reinstalled.

• Tried using rtlwifi.new as a fix.

• Tried connecting through a hidden network, with different networks in different places.

• Reinstalled Ubuntu.

• sudo service network-manager restart

So I thought I would create a new post to get a different perspective here.

Side note: WiFi works perfectly on the Windows side of things, these problems persist only on my Ubuntu boot.

The output of lshw -C network gives:

I use Transmission's Web Interface, but I don't feel comfortable using it remotely (outside of LAN, e.g., from a friend's house) due to the lack of any sort of encryption. The idea of broadcasting my Transmission Web Interface login details, wholly unencrypted, across the internet just doesn't appeal to me for some reason. (I'm kinda paranoid about that. I even installed a browser plugin to enable HTTPS on any site possible.)

I've heard of, and even attempted, a few of the convoluted tutorials involving lighttpd, but I haven't had any luck so far.

I just want to be able to use some sort of encryption for the Web Interface, so I can manage my torrents remotely. What do I need to do?
