Debian - No Widescreen?
I'm currently experiencing some problems when plugging my linux box into a Widescreen monitor / HDTV (using the VGA slot). The problem is that it the driver only seems to support 640x480 and 800x600 resolutions on this Full HD TV / Monitor; however, when plugged into a standard monitor the 'xrandr -q' command shows a vast array of resolutions from 640x480 upto 1280x1024.
This is a pretty skinny install of Debian Lenny using just LXDE desktop and hardly anything else. As a relative newbie to Linux... Can Linux support widescreen / HD resolutions and if so, how do I configure this install to work with my spanking HDTV using the VGA port? Thanks in advance - M |
Something like the following should work for 720p:
Code:
xrandr --output VGA --mode 1280x768 --rate 60 --leftof LVDS Evo2. |
What vga and what driver are you on?
Vesa, the generic usage driver, can't do widescreen. |
Sorry for the late reply and the replies are appreciated!
@evo2 - I haven't got the exact list to hand but from memory the options where 800x600 and 640x480, both with options for 60Hz and 75Hz. That was it. @jim_p - that sounds a bit more like it. I did look into this but couldn't locate where this information is available (and where it can be changed). Sorry, I'm a newbie at the Linux platform so any pointers to obtain this information and react to it would be appreciated. M |
At a terminal do a

I get widescreen with Lenny, and it is a great improvement on what I had before.
It you are new it is worth simply trying ctrl+alt+keypad + to see what happens. You might as well post: Code:
cat /etc/X11/xorg.conf The TV's instructions may say something about the limitations of using VGA. |
Cheers Guys. Here are the output's...

Provided that you have the xserver-xorg-video-openchrome package installed, add this bit in your xorg.conf to "force" it as a driver for usage.

Hey Jim,
That was absolutely spot on! I've now got an issue with the xorg.conf being overwritten on boot but I'll investigate that first before posting a new thread. (Although if you've encountered this before I'll appreciate any pointers). If not, have a good holiday break. M |
I am a total idiot. With "vesa this and vesa that" in my head, I wrote vesa as a suggestion in xorg.conf. Change it to
