I installed Nvidia drivers, but something went wrong, and I ended up with a console. I don't really want to waste my and your time with it right now. So I tried to revert the changes. I uninstalled nvidia-driver and nvidia-settings and ran Xorg -configure. There was also some error. But the final result is, now the X and KDE are running. What I don't know why happened and what's more - how to fix it, is this:

enter image description here

I am without effects and most certainly without HW acceleration and possibly other things.

The integrated graphics card is as follows:

$ lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)<br><br>

EDIT1:
XRender works, OpenGL does not

EDIT2:
$ lsmod:

EDIT3:
xorg.conf file

  • Try lsmod and including the output in the question. – Tom Hunt Oct 28 '15 at 15:48

It looks like the nouveau module is not actually currently loaded. This is likely because the nvidia installer blacklisted it to avoid conflicts, then neglected to undo this when it was uninstalled.

Look in /etc/modprobe.d; there should be one or more files. One of them may well contain a line with

blacklist nouveau

or similar. Edit that file to remove the line, then try rebooting.

  • commented the line, updated initframs and rebooted, no change, how can I help you further, again lsmod? – LinuxSecurityFreak Oct 28 '15 at 16:08
  • It would be interesting to see if the module is still unloaded, so lsmod again might help. You might also run Xorg -configure again with the nouveau line commented. – Tom Hunt Oct 28 '15 at 16:12

  • So nouveau is now loaded, at least. I'd venture the remaining problem is due to leftover configuration crud left behind by nvidia. Other than doing Xorg -configure again, I unfortunately can't really recommend any further measures. – Tom Hunt Oct 28 '15 at 16:19
  • Ok, the nouveau is back. I will start another thread for this issue. Thank you. – LinuxSecurityFreak Oct 28 '15 at 17:20
