Xorg log file
Here is the Xorg.o.log file.
I have the exact same symptoms, i.e.: a) secondary monitor and its modes are detected (with the help of MonitorLayout, b) DAC Type for external CRT is Primary, for notebook's LCD is TVDAC/ExtDAC c) External CRT is blank, probably being in DPMS mode "Off" in my HP Compaq nx7000 notebook, equipped with an Ati Mobility Radeon 9200 and running Gentoo's xf86-driver-ati 6.5.7.3 I tried applying the patch (for modular X) mentioned in bug 3621, but it would not apply cleanly. However, I must say that MergeFB mode (i.e. layout "mergedfbicom" in my xorg.conf) works flawlessly, only simple Dual Head (i.e. layout "xineramaicom") exhibits this problem.

properly in this case)
Georgios, do you use X.org 6.8 or 6.9/7.0? There appears to be a different bug, introduced in 6.9, wherein MergedFB modes work (modulo bug 5565), while Xinerama/plain dual-head layouts produce no signal on the external monitor (bugs 5571, 6165). Russell, did you try MergedFB instead of Xinerama? (In reply to comment #7) > Georgios, do you use X.org 6.8 or 6.9/7.0? X.org 7.0.0, as it appears in the beginning of the Xorg.*.log files I attached. Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future. I have the same problems with a X300SE PCIE DVI+VGA card. So the problem is still present 16 months after it was reported here... Same issue here, using an ATI Technologies Inc Mobility Radeon HD 3650 in a Thinkpad W500. Starting out with either a DVI or a VGA external display connected works fine, but when I try to switch to the other kind of display (VGA or DVI), the display is correctly detected but cannot be activated. For instance, having connected a DVI display to begin with, I tried to activate a VGA display - no use. Here's my xrandr output when I attempted to do so: $ xrandr --output VGA-0 --mode 1600x1200 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 150 (RANDR) Minor opcode of failed request: 21 () Serial number of failed request: 28 Current serial number in output stream: 28 Also tried 'xset dpms force off/on', no use. Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server. |
