Resolution problem in X [SOLVED]

Hi everyone.  I've got a small problem with the resolution in X.  It's currently stuck at 1024x768, but I have a 1920x1080 40" samsung tv hooked up to it.  I tried doing this:
>
> "xrandr --size 1920x1080" but it simply gave the output that the specified mode did not exist.  After this happened, I made an xorg.conf file and added the 1920x1080 mode, but this didn't work either.  If anyone could help, that would be great.

Re: Resolution problem in X [SOLVED]

Can you post your xorg.conf?
Also you might want to try using the --output switch for xrandr

xrandr --output DVI-0 --mode 1920x1080

OR

xrandr --output DVI-0 --auto

You output name will most likely not be DVI-0. Since its a tv, you must have connected it via VGA or HDMI. So you will have to get the output name
and you can get the name of the output  from

xrandr

I am using the vesa driver since I didn't see my chipset specifically listed, which is an intel integrated graphics 82945G/GZ.  I hope that helps.

That's what I though. IIRC vesa supports only a limited set of resolutions.

Try an Intel driver and see what happens.

Re: Resolution problem in X [SOLVED]

HA!  It worked!  I installed the intel driver with the command  "pacman -Qs xf86-video-intel".  Then I replaced "vesa" with "intel" in my Xorg.conf.  Thanks Karol.  Marked as solved.

Re: Resolution problem in X [SOLVED]

xorg.conf in not needed anymore, see the wiki.
You may experience some crashes if it's not the right driver for you, so keep that in mind.
