Public bug reported:
The situation:
- Xubuntu 14.04
- xfce4-settings 4.11.2-1ubuntu2
- xserver-xorg-video-intel 2:2.99.910-0ubuntu1
- Integrated Graphics Chipset: Intel(R) HD Graphics 2000
- HDMI1: BenQ 17" TFT with 1280x1024
- HDMI2: Samsung 24" TFT with 1920x1080
What I did:
- open xfce4-display-settings
- click "identify displays"
What I got:
two little popups that say:
- Display: HDMI1 1280x1024 - on the BenQ TFT
- Display: BenQ 17" 1920x1080 - on the Samsung TFT
This is wrong: xfce4-display-settings puts the label of the first
monitor (BenQ 17") in the popup of the second monitor.
What I expected:
two little popups that say:
- Display: BenQ 17" 1280x1024 - on the BenQ TFT
- Display: HDMI2 1920x1080 - on the Samsung TFT
And now the logs:
grep HDMI /var/log/Xorg.0.log
[ 179.825] (II) intel(0): Output HDMI1 has no monitor section
[ 179.825] (II) intel(0): Output HDMI2 has no monitor section
[ 179.825] (--) intel(0): Output HDMI1 using initial mode 1280x1024 on pipe 0
[ 179.825] (--) intel(0): Output HDMI2 using initial mode 1920x1080 on pipe 1
get-edid -m 0 | parse-edid | grep ModelName
ModelName "BenQ FP783"
get-edid -m 1 | parse-edid | grep ModelName
Call failed
The EDID data should not be trusted as the VBE call failed
WARNING: Checksum failed
Header incorrect. Probably not an edid
So it appears that the Samsung SyncMaster 2494HM does not return correct
EDID data on my system. I don't know if this is the case for this
problem.
