(In reply to Erik Karlsson from comment #50) Created attachment 113754 [details] [review] drm/nv50: Fix backlight not working when PWM_DIV is uninitialised (v4) I redid the patch for 3.18.6. Not sure what the use of removed nvif_rd32() chunk was, but it doesn't seem to be necessary anymore. Could this fix be predicated on the specific PCI ID if the effects are uncertain? No, the value of NV50_PDISP_SOR_PWM_DIVis not derived from the PCI ID. Judging by some other traces I've seen, we can't just unconditionally set 0x5e to NV50_PDISP_SOR_PWM_DIV. Rather, someone needs to step up and figure out how this parameter is correctly determined, which requires some RE'ing work on a laptop that actually has it's brightness controlled by the NVIDIA GPU rather than ACPI or some other backlight component.

[Bug 921321]
Created attachment 85012 drm/nv50: Fix backlight not working when PWM_DIV is uninitialised (v2) V2 fixes the reach of this patch. From what I can tell the PWM_DIV is simply a divider for the initial PWM clock or something, it does not affect the scope of the duty cycle. I therefore assume 0x5e is always a good value to set. Traces from NV50:NVA0 would help verify whether NVIDIA always sets this value or not. This patch requires acpi_backlight=vendor to be set because it tests for the presence of a backlight by testing drm-backlight. An alternative to this test would be checking for the GPIO to be present and routed to SOR, but I wouldn't be surprised if there is at least one device that expects our driver to route it manually.

Congratulations on going stable! I am experiencing this issue as well, and this is the one bug keeping me from using Nouveau. I would really like to have xrandr 1.2 support, so please let me know if there is anything I could provide to help troubleshoot this.

Experiencing a similar issue on a Lenovo W510 (FX880m), Fedora 17 Beta RC3, with the difference that after suspend the brightness is set to max, after that brightness controls do not work (nor do echos to /sys/..).

Did you have the chance to test a kernel that includes the following commit drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issues It does rework the gpio handling and initialization (among other things), that should have positive effect on your issue It is part of linux 3.3rc1 [1] as well as nouveau linux tree [2] Cheers Emil [1] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;h=a0b25635515ef5049f93b032a1e37f18b16e0f6f [2] http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=a0b25635515ef5049f93b032a1e37f18b16e0f6f -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/921321 Title: nouveau: dark screen after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/921321/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

There should be a solution to this dilemma, considering that nvidia's binary blob does it correctly. I got the nvapeek results for using the binary blob, and the results I got are: Before e100: 001c1100 e28c: 0100 e104: 72266640 0441474b e280: 4747 After e100: 001c1100 e28c: 0100 e104: 72266640 0441474b e280: 4747 Notice that unlike nouveau, register 0xe104's content is unaltered after resuming. What is this particular register for? The vbios before suspending is identical between nouveau and nvidia, and it is also identical to the one after resuming with nvidia. However, nvgetbios fails with nouveau after resuming: ./nvagetbios vbios.txt No extraction method specified (using -s extraction_method). Defaulting to PRAMIN. Attempt to extract the vbios from card 0 (nv96) using PRAMIN Invalid signature(0x55aa). You may want to try another retrieval method. Is this a sign that the vbios is somehow wrong/corrupted after resume? Note that I am also using a Elitebook 8530W, with an nVidia Corporation G96M [Quadro FX 770M] card, using Linux 3.1.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/921321 Title: nouveau: dark screen after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/921321/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Emil, thanks. Behavior is unchanged with new kernels.
