how to change monitor from 1024 to 800 at command line


- I installed RHEL3 in a virtual machine.

- My experience is that ALL linux distributions have a problem of not being able to use anything over 800 x 600 in a virtual machine. Perhaps vmware tools fixes this but I have never been able to install it on linux.

- Anyway, so in the RHEL3 GUI (KDE) I changed the resolution from 800 to 1024, logged out, logged in and now it says in a text window:

"I cannot start the X Server. I will disable it until it is configured correctly"

- But now I can only log in at the command line, it won't go into the GUI until fix the monitor settings to a resolution it can handle.

SO... how can I change the monitor settings from 1024 back to 800 AT THE COMMAND LINE?

Thanks,

As root, do
Code:
X -configure
let it finish then do
Code:
X -xf86config XF86Config.new
this should hopefully get you back in graphical mode so you can run the gui configurator again...

Under VMware I am able to get high resolutions, however you need to install the vmware-tools... so alternatively you can try this (you can do this from the command line):

First go in the VMware menu and do "install vmware tools...".
Then in the linux virtual machine do
Code:
mount /mnt/cdrom (depending on your distro, this might also be mount /cdrom)
tar zxf /mnt/cdrom/vmware-linux-tools.tar.gz
this should give no error messages; proceed with
Code:
cd /vmware-tools-distrib
perl vmware-install.pl
Then follow the steps. I hope all filenames are still the same 'cos I have a slightly old VMware version.
If all is well it will have auto-adapted the graphical configuration and you'll be able to choose higher resolutions! I myself use 1280x1024 without any trouble!

Hope this works for you!

Excellent, that gave me the confidence to keep on trying, was a weird problem where the CD was not recognized, finally got it by continually "VM|Install VMware Tools..." and mounting.

Now I have two Linux machines running as WMs at 1152x864.

Thanks!

Great, good to hear you got it working!
When using multiple VMs at once, make sure you have lots of ram (>256) ! vmware can get a bit slow otherwise (swapping)

Oh and now there should also be a small gui vmware tool in the linux VM where you can change some minor settings... but i don't remember the name of the command to run it

cheers,
nukkel
