[SOLVED] Slow GUI (Compiz) on Ubuntu 8.04 (Hardy Heron) using ATI Radeon X300 Mobility

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.

[SOLVED] 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 enable

When 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
