I am a newbie to Linux and I am enjoying it a lot. I have a graphics card driver question.
I have ATI Radeon HD 2400XT and when I installed Ubuntu 14.04 the graphics card driver was installed automatically.
Did Ubuntu install the latest ATI graphics driver or is it a generic driver.
I recently installed cuda along with the nvidia driver which came with it. I then installed updated for ubuntu and when I rebooted the graphics were broken and I could not log in. I think ubuntu may have tried to update the original graphics driver. How do I disable updates of the graphics driver?
