has anyone of you guys already solved the black screen issue after switching to the integrated graphics device?
I have installed Ubuntu 13.04 using just like in this tutorial. Hence I shouldn't have GRUB-Bootloader installed. Nonetheless after installing I found a GRUB Bios partition on my disk. I guess it is not in use but still I dread deleting it before knowing whether it could be useful sometime.
I can use Ubuntu perfectly just until I try to switch output to the integrated graphics device using vga switcharoo. After restarting the Xserver my screen remains black but Ubuntu is still running as I am able to reboot via terminal.
At the moment I use rEFInd to boot Ubuntu in EFI mode. I also tried the kernel params mentioned before:
Unfortunately with no effect so far. The same applies if I only use
i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0 i915.i915_enable_rc6=1 $vt_handoff
Deactivation of the radeon graphics device with results in errors and low graphics mode.
So is there finally a solution to get the integrated intel graphics working with a 13.04 install?
