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:I am without effects and most certainly without HW acceleration and possibly other things.The integrated graphics card is as follows:$ lspci | grep VGA00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)<br><br>EDIT1: XRender works, OpenGL does notEDIT2:$ lsmod: http://pastebin.com/RuG5vJuyEDIT3:xorg.conf filehttp://pastebin.com/2SkLeSkS
Reverting from Nvidia back to Nouveau
graphics;intel graphics
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 withblacklist nouveauor similar. Edit that file to remove the line, then try rebooting.
