KMS:RS780MC:HD3100 default display brightness issue
Last modified: 2011-06-24 04:42:44 EDT
default display brightness issue with RS780MC [Radeon HD 3100 Graphics] on kernel-126.96.36.199-43.fc11 (x86_64):
from what i ran across it was suggested that similar things were related to hardware access layer and kernel because of driver design path changes so that is why i am reporting this against kernel. i hope that is appropriate.
the various video issues noticed since upgraded from fc10 to fc11
( not necessarily related ):
-forgets default screen brightness on reboot so sets to max brightness
(think f10 used to set max until i logged in and then it applied my particluar setting but now with f11 my settings dont see to get applied)
-when go to power manager to reset brightness must move slider bar from its correct position to up few notches before registers change then can move back to original position but now the brightness is where is should be
-as temporary workaround added brightness control to gnome-panel for ease of reset but found that whenever i mouse over the control the brightness again goes to max which is even more anoying lol.
-cant enable desktop effects (not new, couldnt do effects in f10 either)
machine is toshiba satellite L355D-S7901
also ran across similar but different:

Can you test with fedora 12 livecd and report if it works with it.
seems to have problems with fc12alpha x86_64 livecd ( 11.91 ) i downloaded like 10-16-09
when booting it gives me:
"[drm: radeon_driver_load_kms] *ERROR* failed to initialize radeon disabling IOCTL"
also, i noticed that the slider is wacky in that if i mouse over the brightness control while on the scroll section of the touchpad that is what seems to be part of the resetting the brightness when the control gets moused over.
didnt install so couldnt test what happens to saved settings on reboot but seems reasonable to expect that the not finding the radeon will of course give the max response default anyway.
still wishing for 3d effects for radeon, lol. fingers crossed.
ok i still have the forgetful brightness meter problem on one machine with fc11.
now a duplicate machine that had not experienced the problem with fc11 is now having the forgetfulness problem since i installed fc12 on it last week. fun.
yes, still wishing for 3d effects too.
changed to fc12 cause its still here
How about F13 Alpha?
summary: improving but not quite there.
i just downloaded (but didnt install) the 842MB live dvd of fc13-alpha
which is running:
0) brightness applet still looks NOT to work.
when the system boots from the dvd the screen looks to be at full brightness
( which was the symptom of failure for the fc11/fc12 version ).
when i added the brightness applet to the fc13-alpha bar
and try to drag the slider to try changing brightness,
the slide bar does NOT complete a drag but rather disappears during the drag.
i managed to use the mousepad scroll feature
to successfully drag the slider but
that still doesnt change the brightness of the actual monitor
so its stuck at max brightness.
the brightness control applet seems worse because i cant change the brightness.
(i dont know what happens if i do a full install and wont have the chance for probably quite some time due to equip shortage.)
1) you guys rule. the 3d effects engaged!
i was able to turn on the workspace cube function so that
when i click to switch workspaces the cube rotates the screen.
very neet. i was starting to think i would never see that.
cant wait to retry some of the astronomy and cad programs
when i get an install going ;')
i also enabled the window warp-on-drag feature. which worked nicely as i drag my melty window to and fro.
thanks for all the work.

Thank you for reporting back. Updating summary.
Fedora Bugzappers volunteer triage team
noticed these in fc12 '/var/log/messages' when i was looking for something else
(didnt see these in files previously attached) :

Is this a laptop ?
comment#0: "machine is toshiba satellite L355D-S7901"
i finally got around to doing a test install of fc13.
the forgetfull brightness is still an issue.

lshal from a clean install of fc13 from dvd

Xorg log from clean install of fc13
ok this is wierd:
f13_kde seems to work but f13_gnome seems to work only sometimes?
not quite there but certainly getting closer:
0) in comment#14 where i reported continued forgetfulness the system was installed from f13 install gnome dvd.
for starters at least, the gnome install *didnt* seem to remember my brightness settings (though the wireless worked :') ).
however, at some point after installing various programs and 2 days of update cycles the brightness settings seemed to be remembered.
(though the gnome panel brightness control is still a bit flaky in that it jumps around or disappears when try to set level by dragging but was able to set by mouse rolly button).
it was probably an update but it *seemed* like the actually change occured after i installed and enabled xdesktopwaves.
**when time allows, i will be reinstalling f13 from the gnome dvd again to do that re-test and see if i can replicate the fix and to see whether it is related to updates or to some program i installed.**
1) however, in the mean time i just did a test install from fc13 kde livecd and that seems to remember the brightness just fine. yay! (though the wireless doesnt work so i cant just use it lol.)
2) unrelated(?) but at boot kde seems to report:
"pci 0000:04:00.0: no compatible bridge window for [mem 0xfffe0000-0xffffffff pref]"
i will read more on that error and figure out the right place to report it but here for now.
fingers crossed on further testing.
thanks for all the work.
as of fedora 14 beta (kde and gnome) the brightness seems reasonable.
i am able to use sliders in power manager to set brightness.
brightness is remembered upon reboot.
i will leave this bug open until final release of fedora14 just in case.
thanks for the fix :')
(ps: bridge window error still here so must indeed not be related, havent tried compiz desktop effects yet)
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
as of f15 am not getting the 'disabling IOCTL' errors or the GetBrightness errors
(though pci bridge window error still around but unrelated)
(brightness is forgetful again but looking unrelated to this bug
but rather from gnome-settings-daemon issue
so closing or letting expire but if anyone has issues will reopen
