Problem Description:
I crated a bootable stick with the new Xubuntu 26.04 Desktop image and tried to install it, but when the screen launches I am observing the following:
Clicking the Install icon just opens a black window and nothing else happens
Software and Updates opens the window normally, but Xubuntu freezes completely afterwards. I could reproduce it with other windows from the application menu too, but I can’t tell which now.
Other windows, i.e. browser open with smeared colors.
“safe graphics” or “nomedeset” in Grub lead to Xubuntu not even loading. In the loading log there is no error, it just stops loading.
I suspect a problem with graphic card driver that is being loaded, I had similar problems already with Xubuntu 24.04, though not severe. But there I could install the proprietary NVIDIA driver afterwards which solved the problems.
There is definitely something going on with graphics on Xubuntu 26.04, I installed the system just fine last night, no bugs or issues at all, but from time to time noticed very tiny artifacts on screen (I’m on an old Samsung monitor and an old AMD Radeon graphics card), which never before happened to me. I thought it was because of my old hardware.
I opened Hardinfo2 to get some system and hardware information and it said something about missing glxinfo / mesa-utils, which I installed and seems to have made it barely noticeable, but of course this is only possible because I was able to install the system in the first place. Enabling or disabling the compositor didn’t make any difference. Glxgears runs fine.
Can you disable compositing on your live session, to see if the installer works? (I don’t know if this is possible, just thinking aloud here). I can’t try it right now as I’m not at home on my own computer, but I was able to find this and this regarding this issue that apparently only affects XFCE.
Check the links I provided on my previous post. This is an actual XFCE issue. It happened to me too even on a minimal install ISO. Doesn’t affect other flavors.
Post the terminal output here wrapped with code tags (highlight text and click on </> in the composer).
Yeah, that was impossible, no browser or thunderbird works. USB or SSD are mounted but won’t open, any any window can just freeze the system. So I did the best I could, I printed the errors as text and scanned them again.
