need help setting up wide screen LCD


I am running Kubuntu (Dapper) and I have recently acquired a wide screen LCD monitor:

LG L204WT SF (20.1") [1]

I am not using DVI. Just regular VESA connector.

I have been following instructions provided by others [2] but they don't work for me. I have also tried the The XFree86 Modeline Generator [3] with no luck. I cannot seem to compile the cvt utility [4] on my system.

My result is that no matter what I put in /etc/X11/xorg.conf I always end up with a resolution of 1280x1024. This yields a horizontally stretched appearance. What this monitor can do is 1680x1050 and that is what I want.

I would rather not provide xorg logs at this point since I do not have anything logical to provide. If someone can give me methodical steps then I will include logs in a future post.

Can someone provide guidance/comments? Should I return this monitor and get a square one?

Peter

I dont know about Ubuntu/Kubuntu but in Red Hat, Fedora and CentOS you can type the setup command in the shell and you get the option to configure your display, then it generates a whole new xorg.conf file instead of appending or editing the original, basically like when you first install the OS. I have found this has done the trick for me when I moved to a 24" widescreen

Thanks but I understand that the gft utility is for CRT devices. Nonetheless, I will try plugging in the output and report back. This is what I got from gft:

Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync

Looks like the problem lies with my video card.

I'm on my girlfriend's Dell and it came bundled with an Intel card:

i810 (82845G/GL[Brookdale-G]/GE)

Here is what the Xorg.0.log tells me:

(II) I810(0): Not using mode "1680x1050@55" (no mode of this name)
(II) I810(0): Not using mode "1240x720" (no mode of this name)
(II) I810(0): Not using built-in mode "1600x1200" (width too large for virtual size)

Googling led me to the conclusion that this card relies on the BIOS to set its modes and evidently my BIOS does not have what I want:

There seems to be a way to become independant of the BIOS...

Try changing the modeline to:
Code:
Modeline "1680x1050_60"  147.14  1680 1784 1968 2256  1050 1051 1054 1087  -HSync +Vsync
Then also add "1680x1050_60" to the "Modes" subsections. I used the gtf program on my laptop that has a 1280x800 LCD screen. This was before SuSE had any wide screen entries in SaX2 that I could try out.
