My system has RTX 5070 ti GPU and Ultra 7 processor with the recent version of Ubuntu (26.04) installed and have been having some issue with some 3D and video editing software like for example Blender and davinci resolve and even Video playback on vlc is showing artifacts. While searching online i have stabled on similar but not exact issues and fix for theme and have managed to fix some issues. Is there something i might be missing or look into to fix my issues.

My Full Spec is Lenovo Legion Pro 7 16IAX10H movel, Intel® Core™ Ultra 7 255HX × 20 processor, 32.0 GiB memory, NVIDIA GeForce RTX™ 5070 Ti Laptop GPU, Ubuntu 26.04 LTS Linux 7.0.0-28-generic

And the Softwares davinci resolve 20 Blender 5.1.2 - 5.2 Liquigen 1.0.5 Vlc 3.0.23

I recently switched to Kubuntu from Windows 10, and when playing Minecraft specifically, the game tends to freeze up shortly every now and then. Any other game runs perfectly fine.

   Operating system: Kubuntu 26.04 LTS
   KDE Plasma version: 6.6.5
   KDE Frameworks version: 6.24.0
   Qt version: 6.10.2
   Kernel version: 7.0.0-28-generic (64-bit)
   Graphics Platform: Wayland
   Processors: 16 × AMD Ryzen 7 3800X 8-Core Processor
   Memory: 32 GiB of RAM (31,2 GiB usable)
   Graphics Processor: NVIDIA GeForce RTX 5060 Ti (using nvidia-driver-595)

I got 2 spark profiles from playing singleplayer:

jstack: https://pastebin.com/CCenQL8f (different minecraft session from the others)

I had a Thinkpad T490 with a 256 gb nvme 2280 ssd loading Windows11.

I want to instal Kubuntu 26.04 on this laptop. For this I got another 256gb nvme 2230 ssd and connected it to the WVAN port of the laptop.

Windows recognised this drive correctly. Then I boot from Kubuntu LiveUSB and that recognises both the drives as well.

I installed Kubuntu on the new ssd with a partition configuration of 300mb fat32 partition mounted to /boot/efi and boot flag on, and the rest of the drive formatted to ext4 mounted to /.

Install process goes on smoothly and it says Finished. However on reboot (after removing the liveusb), it directly boots to Windows without the dual boot options.

So as suggested in a youtube video, I removed the original 2280 ssd and then reinstalled Kubuntu on the new 2230 ssd using the liveusb (this time used Erase Disk option instead of manual partitioning).

This time again, the install went on smoothly, but when I rebooted after removing the liveusb, it doesn't show boot screen at all. Instead the BIOS asks for a medium to boot from.

I'd like to mention that in case of both installs, Kubuntu shows in the BIOS boot priority list and it didn't work even after putting it on the top of the list.

I am returning to linux after 15 years, so please be patient with me.

I can't directly see the pictures when there are some in the folders, I see the generic picture icon instead of the actual pictures. How to change that ?

Yes "show the thumbnails" is activated on "all files" in the preferences.

I tried debugging with ChatGPT, to no avail.

Thanks

Computer : MSI GT72 dominator pro, Ubuntu 24.04.

I recently created a bootable USB with Ubuntu 26.04 Desktop amd64. The system boots correctly and I can see the GRUB menu, including the “Try or Install Ubuntu” option.

However, after I select it, the system starts loading and then the laptop backlight turns off completely. The screen becomes almost black, and I can barely see a very faint white window (probably the installer). The system seems to be running, but the display is unusable.

When I press e in GRUB, I only see these lines:

set gfxpayload=keep linux /casper/vmlinuz --- quiet splash initrd /casper/initrd

I tried adding boot parameters like nomodeset, acpi_backlight=vendor, and i915.enable_psr=0 to the end of the linux line, but the issue still persists.

Has anyone encountered this with Ubuntu 26.04? Is there a recommended boot parameter or workaround for this backlight issue?

My laptop: Lenovo Legion 5 Pro 16ITH i7 11800h + RTX3050ti

Any help would be appreciated.

Ubuntu version: 26.04

Desktop environment (if applicable): GNOME

I have a customized Lenovo Thinkpad T16 Gen 2, which came with Ubuntu 22.04 LTS pre-installed. About a month ago, laptop’s SSD stopped working and I got it replaced.

I installed latest Ubuntu 26.04 LTS on it, but since install and also during install, system is not able to connect to wireless connections.

If I turn on wifi, it can hardly search for the wireless network installed in the same room. Sometimes it connects to it showing low coverage, but disconnects frequently. Sometimes it doesn’t even find the same wifi network.

I have the same issue with connecting Bluetooth networks.

I am forced to use an internet connection using an Ethernet cable

Also, tried changing default wifi.powersave setting from 3 to 2 in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Please help me to fix this OR confirm if installing Ubuntu 22.04 can fix this.

i have a problem with my steam application

for your Information im not exactly on Ubuntu but on mint but i read it is almost the same thing

it shows the errors down below

This shows when i try to start Steam: You are missing the following 32-bit libraries, and Steam may not run: libGL.so.1

This shows when i open the page in the Application manager: The following packages have unmet dependencies:steam-installer: Hängt ab von: steam-libs-i386 (= 1:1.0.0.79~ds-2)

I tried to get the old steam off my PC but it didnt work i tried to reinstall steam over the browser and the list of missing packages got shorte (it was a lot more before) I tried some Manuals given to me by my Google search wich told me to run sudo dpkg --add-architecture i386 and then put in the command sudo apt install libgk1-mesa-dri:i386 libgl1:i386

Im getting pretty frustrated im trying to fix this for 3 days now and im a complete noob and have no idea about this stuff so please keep it simple

Thanks for the Help in advance

I’m facing a frustrating black screen issue with Ubuntu on my Dell Latitude 5400 (i7). Live USB works great: When I select "Try Ubuntu," everything works perfectly. Graphics are smooth, the screen resolution is correct, and I can use the OS without any issues.

As soon as I finish the installation and reboot, I get a permanent black screen right after the Grub menu. The system seems to be running, but there’s no display.

I can only boot if I add nomodeset to the boot parameters, but this makes the UI laggy and I lose hardware acceleration. Settings and Troubleshooting: Secure Boot is OFF. SATA Mode is set to AHCI.

I've tried both Ubuntu 22.04 and 24.04, and the behavior is the same. Since the live USB works fine, I assume it's a driver initialization issue during the final boot process.

What could be causing the display to fail only after installation? Are there any specific Intel graphics kernel parameters (besides nomodeset) that I should try to get the i915 driver to load correctly?

I tried to dual boot my Ubuntu 24 OS with Windows suggestions of formatting partition to ntfs said to help the Windows installer work correctly, but after formatting with GParted I booted and the boot stopped at grub with message Minimal BASH-like line editing is supported...

I tried the suggestions of installing grub in partition, but I am a new inexperienced Ubuntu user. I finally ran Boot-Repair, but the suggested repair would not act on the boot.

Here is the Boot-Repair report.

Two years ago, I installed Windows Subsystem for Linux (WSL) on my Windows 11 Professional machine. And then due to other pressing issues, I just forgot about it.

Last night, thinking that I didn't have Ubuntu installed on my WSL instance, I installed the latest version of Ubuntu. But then when I went to document what I had done, I discovered that I had already installed Ubuntu into WSL. I am irritated at myself.

The important thing is I am new at using Ubuntu on my Windows machine. I want to do some development in Ubuntu as well as continuing to do development in Windows. But I'm wondering if the two instances of Ubuntu will cause me problems? Should I remove the Ubuntu version from 2 years ago? And if so, how do I do that?

Has anyone successfully used (1) an Intel PC running Ubuntu 24.04, (2) with an installed VIA Technologies, Inc. VT6306/7/8 [Fire II(M)] IEEE 1394 OHCI Controller (rev 80) card, and (3) a Sony DCR-TRV120 Digital8 Handycam?

I just install a PCI FireWire controller to transfer Digital8 video tapes to my PC. After several attempts to follow posted advice, I continue to receive the message, Error: no camera exists. The Handycam appears to be fully operational and supported video control / transfer in the past (~15-20 years ago) using older PCs, but I am having no luck with my current PC. It seems like others have encountered similar issues, and I have not discovered root cause.

Has anyone been successful in configuring and using this type of FireWire device? If so, please share your findings.

I have audacity - at least that opens up. Instructions on Audacity website is for windows only

Tried via the app center Audio recorder (unoffical) = no work Recorder KDE = no work, screws up screen making it flickering and unreadable

Clean new install 24.04 updates done laptop is a HP17

Before I waste any more time trying the next program would anybody please tell me what works because so far I'm batting zero here.

Among snap folders in 26.04LTS x64 Desktop there are 116 files which have the text \x2d embedded in their names - why? ordinary bash utilities such as tar and stat are having trouble with these files, in a backup utility I am writing.

Why embed a backslash code in a pathname?

My Problem is that a group of files is revealed by ls as below (listA).

/etc/systemd/system/snap-gnome\x2d46\\x2d2404-153.mount
/etc/systemd/system/snap-gtk\x2dcommon\\x2dthemes-1535.mount
/etc/systemd/system/snap-desktop\x2dsecurity\\x2dcenter-151.mount
/etc/systemd/system/snap-firmware\x2dupdater-226.mount"
/etc/systemd/system/snap-mesa\x2d2404-1165.mount"

I am using tar to generate lists of files to be used in creating backups (Full and differential) and when it lists the above files it adds a backslash to each occurrence of \x2d and when a copy is tried using the modfied path the following error is generated (listB)

cannot STAT "/etc/systemd/system/snap-gnome\\x2d46\\x2d2404-153.mount"
cannot STAT "/etc/systemd/system/snap-gtk\\x2dcommon\\x2dthemes-1535.mount"
cannot STAT "/etc/systemd/system/snap-desktop\\x2dsecurity\\x2dcenter-151.mount"
cannot STAT "/etc/systemd/system/snap-firmware\\x2dupdater-226.mount"
cannot STAT "/etc/systemd/system/snap-mesa\\x2d2404-1165.mount"

It's not a big problem. I can write a small C filter to correct the sequences. I'm just puzzled as to why the hell was the sequence used at all when - would have done the job and created no problems?

And I'm posting a query on the offchance that I'm highlighting a problem no one else has commentsed on.

I am using Ubuntu 24.04 LTS on an HP Victus laptop. Yesterday I installed all available system updates through Software Updater and rebooted. After reboot: All of my GNOME desktop appearance settings (theme, icons, desktop customization, etc.) were reset to their defaults. When I try to change the appearance again, the Settings application does not work correctly and instead shows "Report a bug to Launchpad". Sometimes after logging in, I get a blank screen and have to force the laptop to shut down before I can log in again. The only enabled GNOME extensions are: ding@rastersoft.com ubuntu-dock@ubuntu.com

I have also noticed that after the update my NVIDIA driver stopped working (nvidia-smi reports that it cannot communicate with the NVIDIA driver), and the system is using the Intel Mesa renderer instead. My questions are: Why were my desktop settings reset after the update? What is causing the "Report a bug to Launchpad" message? How can I restore the desktop settings and fix the blank-screen issue after login?

The only difference between current/selected/highlighted icons in the Alt+Tab switcher is only few percent of gray intensity for background color, which is only visible under ideal lighting condition. If I use any of my 2 laptops in a bright environment with a screen positioned at a slight angle (to reduce glare) then there is no way to see which application is selected/highlighted in the Alt+Tab switcher window. This looks the same on Ubuntu 24 and 26, with Light or Dark theme selected, with high contrast accessibility setting enabled or disabled.

In a screenshot, I see that switcher background color is 34,34,34, while selected background is 74,74,74: (74-34)/255 = 15% If I enable high contrast accessibility setting, then selected background is 94,94,94: (94-34)/255 == 24% So, the difference between high contrast a low contrast is only 9% and it is in the dark part of the spectrum, which only owls can see well, not humans.

My problem is not just with yaru, which unfortunaterly uses close to 50 shades of gray to represent states of objects and it is impossible for human eye to see so many shades, but with gnome/ubuntu, which makes it super hard to modify that setting. I wasted days begging ChatGpt and Claude to give me instructions on how to change that and all I got was one hallucination after another, some of them prevented system from loading and requiring reinstall.

Finally, with help from Claude, I came up with the following procedure, which works:

# On the first run make backup of the original resource
RESOURCE=/usr/share/gnome-shell/theme/Yaru/gnome-shell-theme.gresource
RESOURCE_ORIG=${RESOURCE}.bak # Original
if [ ! -e ${RESOURCE_ORIG} ]; then
  echo "sudo cp ${RESOURCE} ${RESOURCE_ORIG}"
  sudo cp ${RESOURCE} ${RESOURCE_ORIG}
fi

WORK_DIR=~/temp
mkdir -p ${WORK_DIR}
rm -rf ${WORK_DIR}/*
cd ${WORK_DIR}

# Extract original resource to ~/temp directory
while IFS= read -r gpath; do
    local_rel="${gpath#/org/gnome/shell/theme/}"   # strip prefix
    mkdir -p "${WORK_DIR}/$(dirname "$local_rel")"
    gresource extract "${RESOURCE_ORIG}" "$gpath" > "${WORK_DIR}/$local_rel"
done < <(gresource list "${RESOURCE_ORIG}")

# Patch several "background-color" items under various "switcher-list" elemwnts, not clear which of them are really used
BACKGROUND="rgba(255, 255, 255, 1.0)"
PATCH_CSS=("gnome-shell-dark.css" "gnome-shell.css")
for css in "${PATCH_CSS[@]}"; do
    f="${WORK_DIR}/Yaru/$css"
    sed -i '/\.switcher-list \.item-box:selected {/{n;s/background-color: [^;]*;/background-color: '"$BACKGROUND"';/}' "${f}"
    sed -i '/\.switcher-list \.item-box:highlighted/{n;n;s/background-color: [^;]*;/background-color: '"$BACKGROUND"';/}' "${f}"
    sed -i '/\.switcher-list \.item-box:highlighted/{n;s/background-color: [^;]*;/background-color: '"$BACKGROUND"';/}' "${f}"
done

{
    echo '<?xml version="1.0" encoding="UTF-8"?>'
    echo '<gresources><gresource prefix="/org/gnome/shell/theme">'
    find "${WORK_DIR}" -type f | sort | while read -r f; do
        echo "  <file>${f#${WORK_DIR}/}</file>"
    done
    echo '</gresource></gresources>'
} > "${WORK_DIR}/theme.gresource.xml"

# Compile
(cd "${WORK_DIR}" && glib-compile-resources theme.gresource.xml)

# Deploy
sudo cp "${WORK_DIR}/theme.gresource" "${RESOURCE}"

# Reboot (or re-login)
sudo reboot

This works:

But it cannot be so complex!

Also, Claude suggested that there should be a way to modify the Yary theme locally instead of system level, but so far I did not get working instructions.

Is there a better way? Any suggestions?

(By the way, Windows simply paints a thin white rectangle around the selected icon, which is always perfectly visible).

Thank you

I also posted this question at https://github.com/ubuntu/yaru/issues/4477

I am running Ubuntu release 22.04.5 Jammy Jellyfish.
When I connect the USB cables to my desktop, they do not see my Galaxy A16 5G phone?

How can that be repaired?

I have used 4 different cables. It ain't the cable.

Any out of the box thinkers ?

dmesg -W output:

[8354.516445] usb 1-5: new high-speed USB device number 12 using ehci -printer new USB device found, idVendor=04e8, idProduct=6860, bcdDevice= 5.04 Product:SAMSUNG_Android SerialNumber: RZCYA1MSBLV cdc_acm 1-5:1.1 ttyACM0: USB ACM device

I use an Asus E510 laptop. After upgrading from Ubuntu 22.04 to Ubuntu 24.04 the left audio channel is now shared across both speakers on the output device (my TV) and the right channel audio signal is not sent.

Clean booting into Ubuntu 24.04 or Ubuntu 26.04 from a live disk also causes the problem, so it is not a problem caused by a damaged or jumbled upgrade. Clean booting back into Ubuntu 22.04 from a live disk fixes the problem again, so it is not a setting on my TV nor is there anything wrong with my laptop or HDMI cable. I have also tested with multiple HDMI cables to be sure.

There are also issues with the new 5.1 and 7.1 HDMI output modes in Ubuntu 24.04 and onward where the right side channels do not respond appropriately.

This is an untenable situation.

After a routine fwupd firmware update my laptop's built-in screen became very dim, even at "100%" brightness. An external monitor on the same machine looks completely normal.

• Laptop: Dell Latitude 5430, Intel Iris Xe (Alder Lake, i915), internal eDP panel (AU Optronics).

• OS: Ubuntu 24.04, GNOME.

• Trigger: fwupd auto-flashed the Dell system BIOS from 1.36.0 to 1.39.1 (check with fwupdmgr get-history). The screen was fine before that.

What I already ruled out (none of these help):

• Not a kernel regression — dim on every kernel I tried; the panel is only bright in recovery mode / with nomodeset (i.e. when i915 is not driving it).

• Not gamma/ICC — xrandr Brightness 1.0, Gamma 1.0, no VCGT in the ICC profile.

• Not a software brightness slider — /sys/class/backlight/intel_backlight reports brightness == actual_brightness == max_brightness (1023), yet the panel is dim.

• Brightness keys only make it dimmer, never brighter.

• Downgrading the BIOS is blocked: LVFS only offers 1.39.1, so fwupdmgr / GNOME Firmware cannot roll back.

How do I get the panel bright again without a BIOS downgrade?

I've been trying to get my UB600 Bluetooth dongle to work, however it seems that it's not compatible out of the box. In fact, there's only 1 place with a solution how to get it to work however it seems the explanation on how to do it goes over my head. I've tried using what they gave me in konsole but some things just error and I can't seem to get around that. The fix I've been attempting is this. The issue I'm having is, it detects the Bluetooth dongle, but the computer is then unable to detect any Bluetooth devices at all. The lsusb is exactly as shown on that link as is the journalctl.

Is there any chance somebody could explain to me like I'm a 5 year old how to apply that patch, or better yet, create a solution for me? I am running Kubuntu 26.04 on kernel 7.0.0-27-27.

Edit: Following "david" in the comments advice results.

I connect to the internet at public sites, usually my local library, which involves a network login page.

My problem is that before that can happen, the network xfinity often hijacks the login process by connecting itself to my laptop.

How can I permanently ban xfinity network from connecting to me. I use Network Manager on Lubuntu 24.04

Each time my computer goes to sleep the windows change their size. Sometimes they appear bigger, but most of the time, they are smaller. It's hard to tell by how much. Maybe a "titlebar" smaller/larger. It also changes the width by a pretty much similar amount.

I already experienced that issue in Ubuntu 18.04 (I'm on Ubuntu 24.04 now) when using VirtualBox, but now this happens in my regular installation. I'm not too sure what I could possibly try to avoid this issue. It makes no sense to me that the windowing system would just randomly resize windows without user interaction.

Have you experienced a similar situation? Do you have a solution to this problem?

• OS: Ubuntu 24.04
• WM: GNOME Shell 46.0
• Gnome Extensions
  • System Monitor
  • System Restart (showing a button once a restart is required)
  • Failed Services
  • Date/Time with seconds
  • 12 Screens (Cmd-F1 to Cmd-F12)
• I move the bar with icons to the bottom of the screen

Other than that, it's pretty normal in regard to the Gnome system. I don't think I have anything special. I primarily use:

• Firefox
• OpenOffice (Calc/Writer)
• Thunderbird
• Opera
• Gnome Terminal

I also use the tweaks to have some things work normally like the auto-focus of windows by the mouse without having the clicks bring windows to the front.

Update:

I don't know if I changed something, but after a few reboots it started to work as expected and it has not gone back to that weird auto-resize mode on screensaver cycles. So I'm happy now. :)

I have problems with the Bluetooth adapter on Ubuntu 22.04. When turned on from the distribution interface, it immediately turns off.

I have my laptop and Two monitors. I just want to use my two monitors as two separate displays, and don't care about my laptop. Under Settings -> Displays, when I select Join Display, I would have my laptop as display1 and two monitors as display2, so I can not use two monitors as two separate displays. Any Suggestion?

I am very new to Ubuntu and I just installed Ubuntu 20.04 LTS today and trying to setup XRDP so that I can remote -in into my Ubuntu machine from Windows I executed the following steps:

sudo apt install xrdp 

I then tried all of these but only one at-a-time

sudo apt-get install kde-full
sudo apt-get install kde-desktop
sudo apt-get install kde-standard
sudo apt-get install kde-plasma-desktop

echo "startkde"  > ~/.xsession


sudo systemctl restart xrdp

when I try to connect, I get the login screen from xrdp and I select xorg and enter my username and password. But then RDP session ends immediately

Can someone please help me set up XRDP and figure out what might be the issue? I can't stand gnome desktop. I would like to have KDE with XRDP.

Thanks

I am an Ubuntu novice and am looking for some help from experts. I downloaded an Ubuntu app from Windows (I use Windows 10) because I wanted to download Siberian CMS, a free open-source app maker. I have successfully installed Apache2 and am stuck in the installation process for MariaDB and PHP. I have been following the steps in the link attached. Long story short, when I type "sudo mysql_secure_installation" i get "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)". I have been stuck at this phase forever and am desperate for help!

I am doing documentation with rst about my Python project. When using Pycharm I get errors so I tried using another viewer.

I tried restview but had the same problem.

After some reasearch I found my problem here. Apparently is because Sphinx is something apart. So I just need a viewer to render my rst files LOCALLY.

I found sphinx-view but I believe is not working for the moment as I get the error:

sphinx.errors.ApplicationError: Source directory and destination directory cannot be identical

Which I believe has to do with this

I am trying to setup a sftp account to a specific folder. I have created a group ftpaccess and user testuser with home directory as seen here:

sudo addgroup ftpaccess

sudo useradd -d /home/forge/mydomain.com/downloads -m testuser -g ftpaccess -s /bin/false

sudo passwd testuser

sudo chown root:root /home/forge/mydomain.com/downloads

sudo chmod 755 /home/forge/mydomain.com/downloads

Then I have created an transfers directory inside testuser home folder:

sudo mkdir /home/forge/mydomain.com/downloads/transfers

sudo chown testuser:ftpaccess /home/forge/mydomain.com/downloads/transfers

Then I have setup sshd_config like this (rules added to the end of file):

# SFTP account
Subsystem sftp internal-sftp
Match group ftpaccess
ChrootDirectory %h
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
PasswordAuthentication yes

Now trying to sftp with this user sftp testuser@localhost but I get error:

packet_write_wait: Connection to 127.0.0.1 port 22: Broken pipe
Couldn't read packet: Connection reset by peer

What am I doing wrong?

I'm quite new to Ubuntu and want to create a backup. I'm really not sure what files and folders to include so that if I restore my system it will be as it is now. I can't seem to find good details of this anywhere. Hopefully someone could help me with this. Is it possible to backup everything as it is now so in the event of a system restore I don't have to reinstall programs and settings?

I can assign Alt + F1 and Alt + F2 to any function I like in the keyboard configuration window, but it's not being used.

Alt + F1 is always 'dash home' and Alt + F2 is always 'run'.
