Created attachment 76163 [details] Xorg.0.log from i915 This is the Xorg.0.log from Macbook pro 8,2. - Boot - Stop display manager - Power off intel card (See https://bugs.freedesktop.org/show_bug.cgi?id=61114 ) - Swap to intel with: cd /sys/kernel/debug/vgaswitcheroo echo MIGD > switch echo IGD > switch echo OFF > switch - Start display manager - Wait 5 seconds Note that the display only finds 1280x800 - This laptop is 1680x1050 Created attachment 76164 [details]
Xorg.0.log from radeon
This is the Xorg.0.log from the same machine's radeon card for comparison.
Again,
- Boot
- Stop display manager (See above)
- Power off i915
- Start display manager
- Wait

(This is not required on my Hp laptop with another Muxed) Yes. The behaviour is the same if you leave the i915 powered on. Supposedly, the issue is due to the lack of "LVDS reprobing". For a related bug [55311] https://bugzilla.kernel.org/show_bug.cgi?id=55311 It seems to be fixed by the following simple patch which only comment a call to the " intel_panel_disable_backlight" function ...But I am just a end-user so you may want to know what developpers think before trying this... # git diff HEAD drivers/gpu/drm/i915/intel_lvds.c: --- a/drivers/gpu/drm/i915/intel_lvds.c +++ b/drivers/gpu/drm/i915/intel_lvds.c @@ -217,7 +217,7 @@ static void intel_disable_lvds(struct intel_encoder *encoder) stat_reg = PP_STATUS; } - intel_panel_disable_backlight(dev); +/* intel_panel_disable_backlight(dev); */ I915_WRITE(ctl_reg, I915_READ(ctl_reg) & ~POWER_TARGET_ON); if (wait_for((I915_READ(stat_reg) & PP_ON) == 0, 1000)) I attach here a comment from daniel : "The patch itself is imo not safe since it'll break other systems where we really want to disable the backlight. But I have an idea for a slightly different solution. I'll attach a quick patch to the relevant bug reports." Created attachment 78083 [details] [review] Don't clamp backlight when disabling on gen4+ Can everyone affected by this bug please test the attached patch? It hopefully fixes the backlight issues without causing problems on other systems - since on most systems we really want to disable the backlight.

I'm experiencing what may be the same issue with a MacBook Pro 9,1 - however I have a truly black screen (a torch highlights nothing), and there is never any "i915: switched on" line in dmesg. Should I try the patch or open a new bug report? Mine is also truly black - I believe this sounds like the same issue. into rc.local or similar, add a line like dmesg | mail <your email> And make sure you have ethernet connected. This should allow you to see your dmesg. The issue is not a black light issue - The issue is that the display goes completely off. Viewing xrandr is this state shows a different modeline to my display etc. The issue is because the LVDS connection isn't reprobed when the gmux is swapped over. Truely black screen is definitely a different bug here. So please file new bug reports (but drop a link here for references). Thanks. (In reply to comment #10) > Truely black screen is definitely a different bug here. So please file new > bug reports (but drop a link here for references). Thanks. Pretty sure my original bug states: To swap to the intel i915 causes the display to go blank. So the blank screen *is* this bug. I have a macbookpro8,2 and I'm in the exact same situation as reported above. Switchting from DIS to IGD causes the screen to go completely black (nothing is seen even with a torch), going back (blindly) from IGD to DIS brings the screen back. I'm booting using EFI stub via rEFInd. It makes no difference if I add the flags "i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0". I think this bug is already reported in the kernel bug tracker: https://bugzilla.kernel.org/show_bug.cgi?id=56911 (In reply to comment #0) > This has never worked in any kernel versions, but would be excellent to have > fixed. Dropping [regression]. A patchset which is believed to fix this issue was posted to dri-devel: http://lists.freedesktop.org/archives/dri-devel/2015-April/081515.html This patchset enables GPU switching and should at least work on pre-retinas. Please apply it on top of a recent kernel and report back if it works for you. Thank you! Trying to contact Lukas and Miguel in order to see if the patches work for them. @Elio: I've posted a new version of the patch set today: http://lists.freedesktop.org/archives/dri-devel/2015-August/088156.html As mentioned in that mailing list posting, the new version was tested successfully by William Brown who originally opened this ticket. He did mention to me however that he saw various errors and WARN_ONs related to suspend/resume. Just some annoying messages which otherwise did not impact switching negatively. When switching from the integrated GPU to the discrete GPU, i915 reports: [ 36.312399] i915: switched off [ 36.312667] [drm:intel_panel_disable_backlight] Skipping backlight disable on vga switch [ 36.624449] [drm:drm_calc_vbltimestamp_from_scanoutpos] crtc 0 : v 5 p(0,816)@ 36.706235 -> 36.693618 [e 0 us, 0 rep] [ 36.624454] [drm:drm_calc_vbltimestamp_from_scanoutpos] crtc 0 : v 5 p(0,816)@ 36.706244 -> 36.693627 [e 0 us, 0 rep] [ 36.624456] [drm:drm_update_vblank_count] updating vblank count on crtc 0, missed 1465 [ 36.645541] [drm:intel_disable_shared_dpll] disable PCH DPLL A (active 1, on? 1) for crtc 20 [ 36.645558] [drm:intel_disable_shared_dpll] disabling PCH DPLL A [ 36.650037] [drm:intel_display_power_put] disabling always-on [ 46.658101] [drm:intel_runtime_suspend] Suspending device [ 46.686094] [drm:fw_domains_get [i915]] *ERROR* render: timed out waiting for forcewake ack to clear.
