Hello forums,
I already found some other threads corresponding to this general problem, but I was not yet able to solve it for my special case.
The problem:
Currently, after grub and during booting, before I get to the console login(not using a graphical login manager), my screen goes blank/black. I can still log in blind and startx(I can hear skype starting), but the screen stays black. Putting 'nomodeset' as a kernel parameter lets me at least see the console, but since it somehow disables graphics(the driver?) I can't start X either. My system is a laptop with an integrated intel graphics card(HD 4000) and a nvidia graphics card, which I use using optimus/bumblebee.
However, this only started happening today, and after I did some changes:
I did a yaourt -Syu, updating my kernel and xorg(and some other stuff). This uninstalled my patched version of the xf86-video-intel driver, which I installed following the steps outlined under https://wiki.archlinux.org/index.php/Bu … creenclone for using the external hdmi output which is wired to the nvidia card.
After these changes, I rebooted and then had to install the xf86-video-intel from extra, because I was left without a driver, but after installation X started fine.
Here comes the part which somehow caused the error:
I wanted to use the hdmi output again, so I compiled the xf86-video-intel driver from git, but did NOT install it, because I was only interested in the intel-virtual-output tool, which was only available after compiling from git. Again, I only used this program, and did not install the driver from git. After trying different invocations of intel-virtual-output, the last I remember being only './intel-virtual-output', my X server started behaving funny, and after killing it my screen stayed black. Using ctrl-alt-f1 I rebooted blind, and since then I faced said problem of a blank screen.
What I tried:
Uninstalling xf86-video-intel: After uninstalling the driver and rebooting, the screen still went blank, so I reinstalled it.
Disabling the bumblebee-service: Did not help.
Putting 'video=SVIDEO-1:d' as a kernel parameter: Did not help.
any help would be much appreciated!
Edit: I just started X blind, and everything works again. Only thing I changed was add the following to /etc/xorg.conf.d/20-intel.conf:
Section "Device"
Identifier "Device0"
Option "AccelMethod" "sna"
Option "VirtualHeads" "2"
Driver "intel"
EndSection
As mentioned by Gordin here: https://aur.archlinux.org/packages/xf86 … tual-crtc/
Though I have no Idea if that actually *solved* the problem, or the problem just randomly disappeared.
