xrandr laptop monitor flickering
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
I use my laptop monitor (1280x800@60), and an external Samsung
SyncMaster 740T (1280x1024@75) connected via VGA to the laptop. The
configuration is:
~ % xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1824
VGA-0 connected (normal left inverted right x axis y axis)
1280x1024 60.0 + 75.0 59.9
1280x960 59.9
1152x864 75.0 74.8
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 75.0 72.8 66.7 60.0
720x400 70.1
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
1280x800 60.0*+ 60.0
1280x768 60.0
1024x768 60.0
800x600 60.3
640x480 59.9
S-video disconnected (normal left inverted right x axis y axis)
Issuing:
~ % xrandr --output VGA-0 --above LVDS --mode 1280x1024 --rate 75
does work perfectly i.e. spreading my desktop over both monitors, except
for the fact that the lower part of my laptop screen starts flickering
once per 10-15 seconds. The same xrandr configuration was working a
month ago, obviously something happened after some update.
Has anybody else also observed that?
Cheers,
Ivan
