Hi,
Some video modes lead to:
- a black (blank) screen.
- a flickering screen (means, the screen appears shortly, then turns black,
reappears shortly...)
Radeon driver regress: Git version is worst than Debian sid driver. (Also
radeonhd leads to black screens)
Hardware proved to work at 2560x1600 => look like a driver problem.
I tried in past
- with an nvidia card. 2560x1600 worked well with nv driver.
- with the same radeon 3450 under windows. 2560x1600 worked well.
[Connection]
HIS HD 3450 Silence 512 Mb => Radeon 3450 (RV620LE) supports up to 2560x1600
|
dual-link DVI cable
|
monitor dell 3008WFP => flat screen with native resolution of 2560x1600
[Tested drivers]
- sid = xserver-xorg-video-radeon 1:6.9.0-1+lenny4 from Debian sid
- git = radeon git downloaded on 02-Nov-2008
[Result notations]
- F=flicker, means, the screen appears shortly, then turns black, reappears
shortly...
- B=black screen, screen does not appear at all (based on min. 1 min test).
- w=works fine (based on min. 1 min test).
[Results]
Resolution Frequency (as listed by xrandr): results
2560x1600 59.9: sid=B git=B with for git monitor messages 'entering power
save' and just enter a few s before waking up again.
1920x1440 60.0: sid=w git=B with for git many monitor messages 'entering power
save' but in fact never enters
1600x1200 85.0: sid=w git=B
1280x1024 85.0: sid=w git=w
1280x768 60.0: sid=F git=F
1024x768 85.0: sid=w git=w
1024x768 60.0: sid=w git=w
[Below sections may help to understand why]
1) xrandr shows proposed video modes
2) Radeon 3450 details
3) dell 3008WFP details
4) xorg.conf
5) Xorg.0.log after setting xorg.conf to radeon and 2560x1600 with radeon git
