Slow GUI (Compiz) on Ubuntu 8.04 (Hardy Heron) using ATI Radeon X300 Mobility
Posted by Mr. IT Guy | Filed under IT in General, Linux, Operating System
I tried to install Ubuntu 8.04 (Hardy Heron) on my Dell Latitude D610 using the Wubi install method. Everything installs just fine, but I feel that the GUI is very slow. My Latitude D610 is using ATI Radeon X300 Mobility, which I think is not the best video card for Linux. Throughout my experience, Linux is more suited with the nVidia cards.
If anyone has every experienced running Windows XP using a VESA/default graphic card driver at high resolution, that’s how it feels. For those who are not familiar, it feels that the screen refreshes very slowly. For example, when I open up terminal, I can see rectangular dotted outline zooming out before the window pops out. After that it slowly draws the window decoration. Another example, when I scroll a web page on Firefox, the top part of the next page would be drawn first, then half a second later, the lower part is drawn. It is very annoying and almost rendering the GUI non-usable. FYI, the GUI is set with visual effects set to “None”.
I have tried to install linux-restricted-modules, xorg-driver-fglrx, xserver-xgl and the official ATI drivers but to no avail. I have run a check on the fglrxinfo and it’s fine. I even tried the glxgears, but only getting about 60fps.
I am still trying to fix the issue, and will update what I found out later on a separate blog entry.
UPDATE:Fixed HOWTO
vim or vi Works Differently After Upgrading to Ubuntu 8.04 (Hardy Heron)

After upgrading to Ubuntu 8.04 (Hardy Heron), my vim behaves very differently. For example, my vim has a .vimrc entry of
:syntax enableWhen I tried to edit any text file, it will say that it can’t find the command. Also when I press down arrow while in edit mode, it will print out the letter ‘B’ (without quotes). To solve this issue, I have to install vim again by simply running the command
sudo apt-get install vim
