To: SLUG <[email protected]> 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. $ lspci|egrep -i graph 00:02.0 VGA compatible controller: Intel Corporation
