Ubuntu

Desktop effects could not be enabled

Asked by kshitijmmmec

I have been using Hardy Heron from last 2 years and my visual effect settings with Extra option worked fine.
A week ago i installed the release candidate of Lucid Lynx. Everything is good but i cannot change the visual effects from None option to Extra or Normal. It gives an error message "Desktop effects could not be enabled". I am working on a desktop which has Intel 82845G architecture. I installed all necessary packages. Please suggest the soltion for this problem.
Looking forward for the reply.

You may need to form an /etc/X11/xorg.conf file

Have a browse around for examples and try a few. You will need:

gksudo gedit /etc/X11/xorg.conf

to get write access.

the X in X11 is capitalised in the filename, Linux, UNIX and BSD variants are hugely case sensitive.

Webseach around for xorg.conf files for the 82845G/GL and you will find samples you can copy and try. If you use a bad file and don't get a desktop you can boot to root recover mode (hold SHIFT at boot and select recovery mode, then select root and then run:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf_old

Then reboot.

Unfortunately some video cards still need an old school xorg.conf file to make things nice.

Can you help with this problem?
