A number of months ago I purchased an acer X221W, which I have been very
happy with. I was able to get it working in widescreen (1680x1050)
mode by upgrading to the newest (at that time) i810 driver and using
915resolution. Recently I upgraded to a newer version of the Xorg
software, including xf-video-i810-2.1.1, and widescreen no longer works
correctly. When I start X now the display is wrong: text is hidden off
the right edge for perhaps 20 characters, and the visible area stops well
short of the left edge of the monitor. It looks kind of like how I
remember it looking before I used 915resolution to zap the bios mode.
But I've confirmed that 915 is still working. I've tried starting X
with and without running 915resolution, and with and without modelines in
my xorg.conf, and nothing significant seems to change in the xorg.log
file that is produced, or in the behavior of the screen.
I don't remember what version of the software I was at when it worked,
but I downgraded the i810 driver in stages, and if I drop back as far
as 1.7.4, widescreen starts working again.
The modeline I used under 1.7.4 was:
ModeLine "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089
and the ModeLine that shows up in the Xorg.Log.0 file under 2.1.1
is exactly the same, repeated with variations in the hsync/vsync.
X reports that it is using 1680x1050 mode. The monitor says it is in
1680x1050 mode in both cases, with the same refresh rates.
Any clues on how to get this working using the 2 series i810 driver will
be greatly appreciated.
Here's some excerpts from the 2.1.1 log file:
