Question Trouble increasing screen resolution to 1024x800 in Ubuntu - no xorg.conf file!


Hi,

I have set up my Ubuntu virtual machine and am trying to adjust the screen resolution because it's stuck at 800x600 presently and there are no higher resolution options. I've looked at numerous similar forms and tutorials online and they all seem to involve editing /etc/X11/xorg.conf. However, for whatever reason, this file seems not to exist on my machine. I found another tutorial on how to add a screen resolution using xrandr --addmode which added the resolution I want to the list that appears when I type the command xrandr, but when I try to apply it I get an error about CRTC 262 failing.

Help appreciated!

Thanks.

The Xserver isn't recognizing your screen. You have to pick a default or non-brand setting. Once you do get the screen to the right size you want, copy the work xorg.conf and make a back up.

To use a higher screen resolution than 800x600 you have to install the drivers into the guest OS, either VMware Tools for VMware, or the Guest Additions for Virtualbox.

Thanks for the ideas! I'm now trying to install Virtual Machine Additions (for Microsoft Virtual PC 2007), which claims to be able to allow me to change the resolution. When I try to run the installation, a CD image is inserted into my VM. I try to run the program but it says it can't find the autorun program.. except it's in there, I can see it. It's called autorun.inf. How can I get this to run?

Thanks!

Simple answer: You can't. Microsoft doesn't support Linux.

Hi Theruchet,

Under Menu>>Preferences there is an app called Monitors. Have you tried changing the resolution there. I have a system that does not even recognise my monitor, but when I change the resolution it changes. I don't know if you have already tried this, but if you haven't, it might help.

I've heard that at http://connect.microsoft.com/ there is a version of Virtual Machine Additions for Linux (I heard that it supports Red Hat and SuSE... no mention of Ubuntu, which is what I have, though I'm willing to reinstall if I can get this to work). I can't seem to use this website though. I have issues finding anything on it. Comments?

Use Virtualbox or VMware, they support Linux as guest OS. Would be the simplest way.
