Created attachment 26140 [details] switcheroo rc.d script System: Lenovo Ideapad U330 with Radeon 3450 and Intel 4500MHD Arch Linux current with kernel 2.6.34-rc4 (+switchable graphics). Problem: X freezes upon start whenever I try to turn off the discrete card (radeon) using either "DIGD" or "OFF" switcheroo states. The switcheroo states that the discrete card is turned off, and the integrated (intel) card is on, but X freezes upon start. Notes: Not using an xorg.conf file. If I don't try to turn off the discrete card at all it works ok. It works ok also when I do "DDIS" (switch to discrete only) followed by "DIGD" (switch back to integrated only). Please see attached rc.d file which switches modes based on kernel command line. Modules are loaded in the following order: i915, radeon, fbcon. The provided setting works as expected (can switch between X/console, between cards etc).
This problem unfortunately still persists. Procedure start > "DDIS" > "DINT" works, but start > "OFF" doesn't, although the framebuffer is using the intel card to display the console.
is there anything in the xorg log file? I've noticed a race condition in the code, the branch in http://git.kernel.org/?p=linux/kernel/git/airlied/drm-testing.git;a=shortlog;h=refs/heads/drm-nvidia-switch may fix this.
I've tried that, but it doesn't seme to fix the issue. I also get some errors when doing the OFF with an init.d script: Dec 12 10:25:11 tricky kernel: [ 35.696705] ATOM BIOS: Acer Dec 12 10:25:11 tricky kernel: [ 35.696741] radeon 0000:01:00.0: limiting VRAM Dec 12 10:25:11 tricky kernel: [ 35.696747] radeon 0000:01:00.0: VRAM: 3584M 0x00000000 - 0xDFFFFFFF (3584M used) Dec 12 10:25:11 tricky kernel: [ 35.696754] radeon 0000:01:00.0: GTT: 512M 0xE0000000 - 0xFFFFFFFF Dec 12 10:25:11 tricky kernel: [ 35.696762] mtrr: no more MTRRs available Dec 12 10:25:11 tricky kernel: [ 35.696764] [drm] Detected VRAM RAM=3584M, BAR=128M Dec 12 10:25:11 tricky kernel: [ 35.696765] [drm] RAM width 128bits DDR Dec 12 10:25:11 tricky kernel: [ 35.696968] [TTM] Zone kernel: Available graphics memory: 1795484 kiB.
