Dear Linux folks,
TLDR; I am interested if connecting an Intel 915 based device over VGA
to a 1920x1080 monitor works for someone out of the box.
I am experiencing a problem with 915GM based ASUS Eee PC 701 4G laptop,
where `xrandr --output VGA1 --auto` does not give a proper image on a
1920x1080 TV monitor connected using a VGA cable .
The strange thing is that it works with a Lenovo T60 with an Intel 965GM
graphics chip. Also it works when I manually specify a modeline with
$ cvt --verbose -r 1920 1080
$ xrandr --newmode "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 +hsync -vsync
$ xrandr --addmode VGA1 1920x1080R
$ xrandr --output VGA1 --mode 1920x1080R
$ xrandr --output VGA1 --mode 1920x1080R --output LVDS1 --off
The question is, why the 965GM one works and the 915GM one does not.
It could be that the 915GM is not able to provide enough data(?) for a
I thought that it had work sometimes around the end of 2008 and
therefore marked it as a regression. After doing several tests I am not
sure anymore and it could be that a lower resolution was used without me
noticing. I was not able to find a live image yet, with
xserver-xorg-video-intel 2.8.0 or 2.9.0 to test without kernel mode
So it would be awesome if somebody else could test an Intel 915 based
device with a 1920x1080 monitor connected over VGA.
