problem with radeon card

English Hardware
1

Hi all
I have the following problem with my laptop with leap 15.2 installed

For a while, after the installation all worked fine. Since a week, after login or I get a black screen or the desktop freeze. My laptop has a RADEON HD6750 graphic card.
The only way to start is with the “nomodeset” option in the grub and of course it started in low resolution mode. I read in other thread to insert “radeon.dpm=0” and in this way my system start in high resolution mode.
I wonder if it is the right procedure or there is something I can do to solve the problem. I don’t understand why the system worked well for some time and now no more.

Which DE are you using? Gnome? KDE? Other? Which X session? Xorg? Wayland? Does behavior improve if you switch any of these, e.g. use IceWM instead of KDE or Gnome or XFCE? Wayland is more likely to be trouble with KDE than with Gnome, and really has a lot of work left to do to make it usable for many users.

Please visit this primer, then switch from whichever X DDX driver in current use to the other, either radeon to modesetting, or vice versa. Does it help? inxi -G is a quick way to see which X DDX driver is in use, as you can see an example of below.

Uploading Xorg.0.log from /var/log/ or ~/.local/share/xorg/ to https://susepaste.org or https://pastebin.com/ should be done so we can look for clues to the trouble. The command susepaste is a shortcut to upload to susepaste directly instead of using a web browser. It may report failure even though it succeeded. Check here to see if it succeeded. Be sure the Xorg.0.log file you upload is from a normal boot and login attempt, not one using nomodeset.

Uploading output from the following should also be useful:

sudo journalctl -b | grep ailed

If it’s only two dozen or less lines, pasting here using code tags instead of uploading should be fine.

It should not hurt anything to try radeon.dpm=0 or radeon.dpm=1, as one does it for a single boot by using the E key at the grub menu to append it to the line beginning linu, which only affects the current boot.

I have a similar GPU, though not a laptop, and it’s working fine using TDE:

Hi mrmazda

I use KDE with Xorg, my Xorg.0.log contains https://susepaste.org/30003356

This is the results of inxi and it appears that I used radeon DDX

and this is the output of journalctl

Can it help?

In any case, I tryes also to install other distros (mint and fedora) with the same problems. Only win10 works fine

According to the log, X is trying to use two DDX drivers. Let’s try using only one:

sudo zypper rm xf86-video-ati

Once done, the next log should show modeset(0) but not RADEON(G0).
