dmesg output of switching to Nvidia GPU, turning Intel card on and switching back to Intel card
(In reply to comment #0) > AFAIK the Nvidia graphics card sends its output to the Intel card, which is > responsible for the graphics output to the screen. So I guess the problem is > that switcheroo disables the Intel card which causes the graphics output to > stop. If you don't have a hardware mux, stay away from vgaswitcheroo. Take a look at http://nouveau.freedesktop.org/wiki/Optimus/. Please try this with 3.11.10 or 3.12.2 or 3.13-rc2. There was a patch that could help NVC1 cards included in all 3 of those (well, it went into 3.13-rc1). https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=13d2b35a065399 . Note that 3.12+ also have runtime pm for optimus setups, which will automatically turn the nvidia card on/off depending on whether it's being used (in theory). -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 85566 [details] lspci output First of all: you did a very good job! Actually I wanted to report an X server crash and a kernel panic in nouveau/vgaswitcheroo in Ubuntu 13.04, but now that I installed the latest version of nouveau I see that these bugs are gone! However, there are still some other bugs in the latest version that I want to report. Kernel version: 3.11.0-031100-generic DRM version: 1.1.0 20060810 Nouveau version: 1.1.1 20120801 I did a out-of-tree compilation using the nouveau snapshot of today. My notebook (Medion Akoya P6624) uses a Nvidia GeForce GT 425M together with an Intel HD graphics card. X is not involved in these reports. I always booted to console and never started X. To make it clear how long a command took to execute, I used a script that logs to dmesg and syslog when a command started executing and when it was done. The commands of each report were executed directly after boot. The output of "cat /sys/kernel/debug/vgaswitcheroo/switch" after boot is always 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 1) Switching the dedicated card off takes 45 seconds and reports some errors 1.1) Switch dedicated card off: dmesg output: [ 109.787177] Before "echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" [ 109.787404] VGA switcheroo: switched nouveau off [ 109.787476] ACPI Warning: \_SB_.PCI0.P0P1.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130517/nsarguments-95) [ 109.787830] nouveau [ DRM] suspending fbcon...

So I guess the problem is that switcheroo disables the Intel card which causes the graphics output to stop. I would be glad if someone could take a look at these issues. Please let me know if I should supply more logs or try out a different version.
