[SOLVED]how can I get highr screen resolution ?

[shalom938]

I installed wheezy on a new pc, and I have only two resolution modes:
1024X768
800x600

what do I have to do to get hight resolution?

Does your monitor support higher resolutions?
Have you installed xserver-xorg-video-intel?

[shalom938]

my monitor supports higher resolution. I'm dual booting with windows 8 (sorry,i got it with the computer) and there I have higher resolutions.
xserver-xorg-video-intel is installed.

Its a uefi mode boot if it makes any difference.

Windows 8 with higher screen resolution does not mean that your monitor supports higher resolutions.
Your graphics card supports 8192 × 8192, but monitor probably does not.
Which model of computer do you have?

ok, I don't understand that. how come?

Its a pc, not a laptop. its a fujitsu PH300.
The screen I use is really very old LG screen, its about 6-7 years old. there are setting on the screen itself where it says:
preset mode: 1024X768 60hz

[ruwolf]

(I have thought that it is some new netbook. Laptop is kind of PC for me. Desktop is other kind - probably this one.)
OK, is there model name on back side of your LG monitor? Or somewhere else? (This information about model number should be in menu in monitor settings available by buttons on front and bottom side of the monitor. It should by in /var/log/Xorg.0.log too, but there is lot of other infomration.)

[shalom938]

ruwolf Thanks for your help.

this is my monitor: http://reviews.cnet.com/lcd-monitors/lg ... 10460.html
manual: http://www.manualowl.com/m/LG/L1730S/Manual/244321

it says that it supports 1280 x 1024 at 75.0 Hz but I have no idea how to adjust it.
I try the on screen menu but can't see how.

[ruwolf]

Hmm..., it seems that your graphics card can not generate signal for higher resolution for this monitor...
Can you look in /var/log/Xorg.0.log and put here lines from it?
Desired continuous section should contain phrase EDID Version:, start with line containing EDID for output and stop with line containing DPI set to - it is cca 100 lines long or so. (Whole /var/log/Xorg.0.log may be too long and with lot of information not directly connected with this issue.)

Please, this is not 1 continuous section,
this is collection of grep-ed lines, which are separated by other "ditched" lines.
(I think it may be better if we can see whole /var/log/Xorg.0.log like this excisions.)

^^ This.
Seems quite clear.
X server asks monitor "What can you do?"
Monitor replies as above.
X server says "OK, 1024x768 it is..."

[ruwolf]

In my opinion your computer (X server) cannot read capabilities of your monitor by cable - I do not know why.
But you can set it in configuration file(s).
Do you have file /etc/X11/xorg.conf?

[shalom938]

I don't have /etc/X11/xorg.conf , I tried creating it but I got the same error as this:
viewtopic.php?f=30&t=64282

[ruwolf]

OK, but I must warn you.
(I have edited these files several times, I had different cards with different monitors but I do not remember all requirements yet - I have consulted man xorg.conf now.)
You must repeatedly check that frequencies (HorizSync & VertRefresh) are correct. They say that wrong frequency sometimes is able to harm old monitors.
This configuration may not be functional, so your X server may not start - you must then rename/move/delete this configuration file by console and restart your X server.

This is my suggestion for your /etc/X11/xorg.conf file:

Of cource, you can erase depths/modes which you do not like or change your default (color) depth etc.
