[Nouveau] [Bug 29685] New: DPMS does not turn off LCD backlight on NV18 [GeForce4 MX with AGP8X (Mac)]
https://bugs.freedesktop.org/show_bug.cgi?id=29685 Summary: DPMS does not turn off LCD backlight on NV18 [GeForce4 MX with AGP8X (Mac)] Product: xorg Version: 7.5 Platform: PowerPC OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy: rechner at vlado-do.de QAContact: xorg-team at lists.x.org I'm using bug #19356, which describes the same problem with a different iMac, as an orientation for my bug description. Expected: $ xset dpms force standby; should turn off LCD backlight. Actual Result: Screen is black, but LCD backlight stays on. Workaround: Use nv driver. Some information on my system is already in bug #29455 (video bios dump, register dump, "lspci -vvnn" output). I downloaded, compiled, and ran radeontool, as was described in bug #19356: nouveau driver: DPMS on: 0x0060081c 0xa2565051 (-1571401647) 0x000010f0 0x84830535 (-2071788235) DPMS off: 0x0060081c 0xa2565055 (-1571401643) 0x000010f0 0x84830535 (-2071788235) nv driver: DPMS on: 0x0060081c 0xa2565051 (-1571401647) 0x000010f0 0x84550535 (-2074802891) DPMS off: 0x0060081c 0xa2565050 (-1571401648) 0x000010f0 0x04550535 (72680757) -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=29685 --- Comment #2 from Vlado Plaga <rechner at vlado-do.de> 2010-08-21 04:59:32 PDT --- (In reply to comment #1)> The attached patch should fix it, can you give it a try?Yes! Great! Thank you! Now for me nouveau is superior to nv in every aspect... except for "installation", maybe. ;-) First I tried the patch with Ubuntu 10.10's kernel sources (2.6.35), and it was applied without complaint, but the compilation failed with drivers/gpu/drm/nouveau/nv04_dfp.c: In function ?nv04_dfp_update_backlight?: drivers/gpu/drm/nouveau/nv04_dfp.c:454: error: implicit declaration of function ?nv_mask? make[5]: *** [drivers/gpu/drm/nouveau/nv04_dfp.o] Fehler 1 make[4]: *** [drivers/gpu/drm/nouveau] Fehler 2 make[3]: *** [drivers/gpu/drm] Fehler 2 make[2]: *** [drivers/gpu] Fehler 2 make[1]: *** [drivers] Fehler 2 make[1]: Verlasse Verzeichnis '/usr/src/linux-source-2.6.35' make: *** [debian/stamp/build/kernel] Fehler 2 Then I tried the official 2.6.36-rc1, and the backlight can now be switched off properly. Unfortunately the EDID error mentioned in bug #29455 is also back again. Will that bug be fixed in 2.6.36-rc2? Can I just replace the "gpu/drm/nouveau" directory? Or should I take the whole linux tree from nouveau's git again? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
