limited to 640x480 resolution

[Giles]

This may be a bit greedy, since this I kind of covered this in this thread, but the title of that thread is no longer accurate: the problem described in that title is solved, and a different one has arrived, so i thought it was worth posting a new topic.

basically, I can't change the resolution on a anything other than 640x480. I am using an Intel 845 graphics card and IBM G76 monitor.
Here's my xorg.conf (somewhat different to that I had when the last topic was posted)

Any help gratefully accepted ;- ), and thanks for taking the time to look at this

Erm, it all looks ok, have you tried changing resolutions with Ctrl+Alt+ the + and - keys on the numpad?

yeah - nothing happens, I'm afraid

thanks anyway

Can you post up some details of your monitor? Resolution and Size etc. Also have you modified this xorg.conf by hand? Was your monitor listed or did you configure it step by step through xfdrake?

[Indigno]

well, most likely, you simply have it configured wrong, or perhaps that video card requires a certain driver to run. keep trying, I'm having the same prablem (except that mine's so off i cant even get to the GUI)

[Giles]

Thanks for the replies, guys.
I have quite a busy weekend ahead, so I may not be able to give any feedback until monday (stupid time to start a topic, really, wasn't it ), but please don't think I'm ignoring your help...

Thanks again

A proposition : using your distro's install DVD/CDs, run an "upgrade", and in the menus, chose again your graphical card AND your monitor, AND chose a generic monitor. A generic monitor should be 800x600 for a start : that's already better ;o)

It's an IBM G76 monitor (16 inch), but I'm slightly confused as to what you mean by the monitor resolution - is that just the max at which it can be used? In windoze I can use it up to 1600x1200, if that's any help. I have modified the xorg.conf myself: the original is shown in this topic, but before the changes were made the situation was worse (as described in that thread, the monitor was shakey and the gui was larger than the screen size). My monitor was listed, as was my graphics card.

well, most likely, you simply have it configured wrong, or perhaps that video card requires a certain driver to run. keep trying, I'm having the same prablem (except that mine's so off i cant even get to the GUI)

Yeah, it just seems rather odd to me that I'd be able to get to a perfectly stable situation at all, were a driver missing or anything seriously mis-configured - perhaps I'm answering my own question: perhaps it's just a minor misconfiguration somewhere... I can cope with things either working completely or not at all, I get easily confused otherwise

...run an "upgrade"...

An excellent idea, were it not for my slight(?) incompetence: that particular comp is connected to the network via a belkin USB adaptor, for which I'm pretty sure there is no linux driver - OK, then, use ndiswrapper and the windows driver off the belkin CD. Great plan. Shame I can't tell which file is the driver (none have the .drv extension, and i dont know how to find out which file windows is using)...
EDIT: the list of files on the cd is here, if anyone thinks they could identify the correct file...

Thanks again, all three of you guys

I found this one here- I've modified it slightly because it was set for two monitors. This is also for an ATI card so, it's mostly for reference. I find the modelines are the most important thing, a few misplaced digits are enough to take it down. There is a whole lot of ATI bits there, I didn't want to guess at substitutions for your setup.

I had this problem and changed the monitor setting from 24 bit to 16 bit and got it working without any problems.
