The graphics driver is a software module that works with a system's video card / graphics adapter [1]. Even though most graphics adapters are onboard and not expansion "cards" any more, the term "graphics card" is still used frequently.
Contrary to Windows, on a Linux base system you do not need to have a driver for each and every card, in fact there are universal drivers that handle multiple chips from within the same software. This makes it easier as on Windows - however, there are often competing drivers out there, mainly drivers made by companies themselves vs. open-source projects and forks of open-source projects.

Force using a specific graphics driver
If you experience graphics-related problems, you can force the system to use a specific driver. To do so, use the parameter "Graphics driver" under the Display options. You can do this locally on the client or in NoTouch Center, for groups or on a per-client basis. If you change this parameter, you should reboot the system afterwards.
The parameter is a text field and requests to type in a driver name. See below for driver names. An alternative that should alway work is vesa. Type in "vesa" without the quotes to activate this.
What graphics drivers are available?
The most universal driver is vesa (VESA mode). With VESA mode more advanced features like multimonitor might not work though and it is not as fast as other drivers but it may be enough to get a basic VDI endpoint setup up and running.
- Everybody can use vesa as a fallback.
- NVidia card users may try both nv and nvidia.
- ATI graphics card users may try radeon and fglrx.
- VIA chip users may also try via, via2 and openchrome.
How can I change the graphics driver if I don't see anything?
Easy: use the browser of another machine to connect to this machine - see Configuration#Remote access for more information.
What if that all fails?
