Ouput of intel-virtual-output -b -a -f
I just tried out the new intel-virtual-output tool as replacement for
screenclone.
Currently I'm using it on my Lenovo T510 with Optimus with a triple-head setup
(VGA on the left, notebook in the center, VIRTUAL on the right).
I start the setup with the following commands:
kathib at kathib-notebook:~$ sudo optirun true
kathib at kathib-notebook:~$ intel-virtual-output -b -a -f
and then use "arandr" to set the screen resolutions and positions of the
monitors.
The problem is, that intel-virtual-output offers only "800x600" as screen
resolution for VIRTUAL5.
With this screen resolution the tripel-head setup works like a charm. But
800x600 is a really sick resolution so I tried to add a newmode to xrandr:
kathib at kathib-notebook:~/xorg_debug$ sudo cvt 1280 1024 60
# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063
-hsync +vsync
kathib at kathib-notebook:~/xorg_debug$ sudo xrandr --newmode "1280x1024_60.00"
109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
kathib at kathib-notebook:~/xorg_debug$ sudo xrandr --addmode VIRTUAL5
1280x1024_60.00
After this I changed the resolution of VIRTUAL5 with "arandr" to 1280x1024
which ends with no signal on the 3rd Monitor.
You find the output of intel-virtual-output in the attachement
(intel-virtual-output.log), debugging in tools/virtual.c was enabled.
I then have to kill and restart intel-virtual-output to get the 3rd monitor
working with 800x600 again.
Any ideas why intel-virtual-output offers only 800x600 and why it does not work
with the newmode of xrandr?
Thanks!
