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-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
ReportedBy: rechner-dLI15PoULosb1SvskN2V4Q@public.gmane.org
QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.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)

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. _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau ^ permalink raw reply [flat|nested] 5+ messages in thread

That works sometimes, if the internal APIs haven't been broken between the kernel versions you're trying to mix, but no guarantees. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau ^ permalink raw reply [flat|nested] 5+ messages in thread
