DELL Precision 3650 + EndeavourOS + SDDM incompatible?

After 3 half days of trying to install EOS Artemis (22_6) with Plasma/KDE using default options, I am still unable to use EOS with SDDM. When I booted the new install, the expected GRUB menu was displayed. So far, so good. But when the desktop was displayed, I found the following problems:

  • Blurry text and “vibrating” windows; yet the live demo was razor-sharp & rock-solid
  • Most options on most menus are unresponsive
  • Each of the 4 app icons near the applications button on the panel bar partly overlap the other 3
  • System Settings were not responsive/viewable
  • Sometimes there is a very light pink hue or “wash” over much of the screen
  • The location of the panel bar can be changed; but the panel-bar size cannot be changed
  • Some keyboard options – such as Ctrl+Alt+t – do not work
  • At one point, the entire screen displayed “No Windows” – I could not reproduce this
  • No apps can be run, no screenshots are possible, and the CLI is unreachable
  • All the above issues were under SDDM … everything seems to work OK with the other 3 DMs

To me, this suggests Plasma/video issue. But what? I found “sddm 0.19.0-8” as well as “sddm-kcm 5.25.2-1” both installed. My 2nd and 3rd re-installs made no difference. And, yes, the CRC was good before I made the USB flash drive for installation.

The system info below was obtained by running “inxi -FAZ --no-host | eos-sendlog” from the live demo.

Try to disable the compositor. The first option in the compositor window.


If that doesn’t help, from a terminal
$ pacman -Q xf86-video-intel

If it shows installed, try to uninstall it and reboot

You also have nouveau as the Nvidia card driver, it may be a suboptimal choice. Likely the proprietary nvidia driver works better.

See EndeavourOS wiki or Arch wiki for more info about the nvidia drivers.

I agree with removing xf86-video-intel and installing nvidia drivers. I think i would try both of these before disabling the compositor. That may be required also.

Thanks to all 3 of you for your ideas. It seems my best action would be to disable or remove the intel and nouveau drivers, add the proprietary nvidia driver, and (maybe) disable the compositor.

As you recall from my earlier description, I cannot open Konsole / CLI to enter commands. All the Systems Settings I tried are unresponsive. I’m thinking that either from my fully functional Manjaro on another partition or maybe from the EOS live demo on a USB flash drive, I could use the CLI to make the driver removals and NVIDIA driver addition in the directories of the limited-functional EOS. But to do that, I would need to know which files and directories. Does this strategy make sense, or am I barking up the wrong tree? Or maybe I should try those driver changes from one of the other DMs in the installed EOS with the SDDM issues. So far, my limited testing shows the other DMs function as expected.

Are you able to boot and get into a TTY?

Edit: If not you could boot on the live ISO and Arch-chroot

Thank you for the link. I am able to boot into SDDM GUI (via GRUB) as is, but most of the desktop menus, links, panel bar options, etc. are not usable in SDDM. Other 3 DMs seem fine. I won’t be able to try your suggestion until late tomorrow (Sunday) but will let you know the results when I do.

It was suggested to install the nvidia drivers and remove xf86-video-intel and reboot.

Gentlemen…thank you! Your analysis and solution to my problem of EndeavourOS being unusable with sddm (Plasma/KDE) was exactly right. Video drivers were the cause of the malfunctions.

Since I don’t know diddly about downloading, removing, and installing video drivers, your assistance, some Googling, and trial & error were required to get a fully functional installation of 22_6. I am impressed by Forum members’ quick and knowledgeable responses, which means I won’t need to find an alternative to EOS.

The actions I took to resolve the video drivers problem were:

  1. After booting EOS into unusable sddm, on Welcome Screen, switch dm to fully functioning gdm
  2. In Konsole / CLI, type: pacman -Q xf86-video-intel
  3. Type: sudo pacman -R xf86-video-intel
  4. Type: pacman -S nvidia-installer-dkms
  5. Type: nvidia-installer-dkms
  6. Switch dm from gdm back to sddm
  7. Reboot to restart EOS under sddm

No changes to the compositor settings were required.

Today I begin installing & configuring applications and look forward to great times with EOS.
