[SOLVED] Can't find higher resolutions

[ChipOManiac]

Well I should have expected some fighting

My laptop's resolution is currently set at 1024x768.

I don't think this is the maximum, since when I bought it the other day, it was at a resolution of 1366x768 (Windows 7).

But strangely, I can't find anything higher than 1024x678 (low is at 800x600) in the display settings.

Have I screwed something up during the installation for it to come out this way? If so what do I have to do to correct this?

So far I've tried using xrandr to set the resolution, I used:

• "cvt 1366 768" to get the modeline
• then created a new mode via "--newmode"
• added it to "default" via "--addmode"
• then tried to use the new resolution from the display settings

So far nothing has worked.

Does anyone know what might be wrong? And In case I'm wrong, you're free to slap me on the head

Edit:
My screen is a 15.6", if that's of any use.

did you try and set the new mode with xrandr? you might get some more help posting some xrandr output, but there are a lot of similar threads on here, you should do a good search or two like 'resolution' with the driver x is using, and your hardware.

Yes I tried doing that. Here's the output

Do you think it's something with my kernel version, looking at the other threads makes me think I might have a similar problem.

xrandr: Failed to get size of gamma for output default

that's a good error message to search on, seen that a lot. check /var/log/Xorg.0.log using vesa driver or something weird like that?

[phenest]

What video card make/model are you using? 1366x768 might be unobtainable with whatever driver you're currently using.

According to lspci the card is a

Seems like it loads both the Intel and VESA drivers

Sandybridge Intel drivers need a minimum of the xorg and Intel video driver in squeeze-backports, plus an upgrade to the 3.2 backports kernel (and a boot to it).

I see, I had a little bit of a hunch that this might be the problem, but I wasn't too sure. I'll do this as soon as I get home. You have my thanks sir!

[ChipOManiac]

Welll I upgraded the kernel, xorg, and intel driver from the backports. Could see the effects just after I restarted, now I'm at 1366x768, and happier.

Thank you stevepusser. And thanks to phenest and bw123 for helping me out.

Thread solved.

Glad to see the problem is fixed--there's been one or two threads a day for the last week or so that express the same issue, so it's not really hard to come up with the fix!
