How to install Ubuntu on a dell laptop

My dell laptop hasn't reinstalled the system for two years. It's a mess. After a long time, I decided to reinstall the system and install Ubuntu. I installed Ubuntu8.10alternate. I encountered two minor problems during installation. One problem was that the screen flashed after entering the installation interface and the screen was constantly refreshed, so I could not see anything clearly. Later, it was found that the external monitor was normally displayed, and the external monitor was switched back to the notebook screen without flashing. Another problem is that after installation, the system crashes after a few minutes of entering the system, and nothing can be changed.

My dell laptop hasn't reinstalled the system for two years. It's a mess. After a long time, I decided to reinstall the system and install Ubuntu.

I installed Ubuntu 8.10 alternate and encountered two minor problems during installation.

One is: after entering the installation interface, the screen will flash, and the screen will not be clear without stopping refreshing. Later, it was found that the external monitor was normally displayed, and the external monitor was switched back to the notebook screen without flashing.

Another problem is that after installation, the system crashes after entering the system for a few minutes. Nothing can be changed but the mouse can be moved. Later, it was found that the 3d effect was removed from the screen settings and the system would not crash, now, you can use the ATI driver to enable 3D effects. It seems that my ATI independent graphics card is subject to the default driver in the system.

Another problem was encountered. The Notebook used a combination of keys to adjust the brightness. As a result, the system crashed, and the menu and keyboard failed. Found from the Internet: it should be the problem of driving acceleration. Modify xorg. in the conf section "Device" section, adding Option "SWcursor" does not solve the problem according to the above method. Now I have to add a brightness adjustment tool to the task bar, you do not need to adjust the notebook combination.
