Does anyone have on hand an xorg.conf modeline for a DELL U2410
running at max resolution of 1920x1200?
Or otherwise how can I calculate such a modeline from the monitor specs?
I've tried the 1920x1200 modelines from mythtv.org, which has
modelines for a Dell 2405FPW.
My laptop can drive the resolution - previous monitor was an AOC of
same size + res. However it is only now that I finally constructed an
xorg.conf with dual-monitor support, with the AOC, I was running only
external monitor, or internal, not both at same time. It was a very
simple xorg.conf essentially with just the extra bits for the marble
trackball and touchpad.
I've tried with no xorg.conf and got presented with max 1280x800,
which is the internal resolution. With a lot of googling I eventually
determined an xorg.conf which displays both monitors in non-clone
mode, and on independent resolution, but with max external resolution
of 1600x1200.
gnome-display-properties is showing the correct available resolutions,
including 1920x1200, but when I choose 1920x1200 for the external
monitor, the U2410 flickers with a fuzzy image - I guess the timings
being sent to monitor are actually incorrect.
When I move mouse from external to internal display, the external
display is black, the internal laptop screen doesn't flicker, but is
completely skew-wiff (overlapping images of desktop which are all on
angles and interleaved).
Going back to 1600x1200 on external and 1280x800 on internal, things
go back to normal.
After day of battling yesterday, I eventually found enough hints to
piece together the xorg.conf below which gives me dual monitors, and a
decent resolution.
Reson I'm on such old kernel/distro: About 6 months ago I tried latest
Ubuntu release at the time, and the intel 855GM graphics drivers kept
causing my laptop to hang, so I've reverted to Hardy/ 8.04 LTS, and
also older kernel, even for hardy. Contributed to at least one bug
report on this and have not had time in last two months to check
latest kernels/ xorgs etc.
