Screen resolution

[jsaturno]

Hi,

I installed mandriva 2007 recently and I only can use the 800x600 resolution (no more). All the drivers are right (Intel D965) and I have a Samsung SyncMaster 550V Monitor...

Why can't i use a 1024x768 resolution????

Please help me...

1024x768 is really there... It appears to be a supported resolution for my card but when i set it my monitor is like in stand-by...

[devils casper]

check your Monitor Manual and note down supported VertiRefresh and HorizSync rates. open /etc/X11/xorg.conf file and set correct rates in file.

Hey,

The xorg.conf is right! There are the right values for VertiRefresh and HorizSync...

But in all the subsections "Display" I've seen the '800x600', '640x480' ...

Why there is not 1024 option?

[devils casper]

its not configured to use those refresh rates. add 1024x768 manually in xorg.conf file.

Hi casper,

I configured the xorg.conf file manually and when i restarted my computer the monitor was in stand-by... Like if i set the 1024x768 resolution in the configuration menu.

It's not working.

I really don't understand that... If anybody have the Intel D965 chipset and knows how to do it please help me!

[devils casper]

its not chipset problem. Display depends on Video Card and Monitor. Post Monitor and Screen Sections here.
