You first consider these:
1. Your platform. What model and version of HD are you using?
2. Your kernel version.
3. Your architecture.
Always backup everything (much your root system files, including your kernel), then you can try. I am running sandy bridge but it is okay. The current version bundled in Slackware 14 is xf86video-intel2.19.
When I play video, or do anything remotely graphics intensive, there is a very feint clicking sound coming from my ThinkPad..... weird. Hopefully, a driver update will fix this.
If it is for these 'alone' there is no need to tinker with the whole driver set. Remote operation is highly prone to signal interference. Another possibility is the monitor conditions receiving the signal.
