Recently got a weird issue after applying an Nvidia driver update from the official repository.

Each time I boot, the computer hangs on run level 3 and fails to give me graphics. The recovery mode works fine though. The output of /var/log/Xorg.0.log is shown below.

This issue occured after I executed nvidia-xconfig, which will generate a new xorg.conf file. After a long time of searching and trials, including reinstalling the drivers and messing with bumblebee. I find out the solution is super easy: just remove /etc/X11/xorg.conf, OpenSUSE (or maybe all the up-to-date distros?) is smart enough to select the proper drivers and hardware to handle the graphics.

And I'm using an Nvidia optimus card together with an Intel integrated card, if anyone is interested, here's the output of my video card info.

$ lspci |grep -i vga

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