That's an option of course, but not necessary. The distribution
supplied driver very much does support and work with resolutions
as high as the hardware supports. I use 1600x1200, and test with
1920x1440 and 2048x1536 as well. So changing video drivers isn't
going to likely change anything.
The maximum resolution problem is tricky to resolve - could be a
lack of the resolution in the screen block, or bad refresh rate
settings for your monitor.
Not really tricky at all. The X server log file will indicate
directly what modes were rejected and why for every known built
in video mode the X server supports. That information tells you
why a video mode is not available, and is almost always due to
misconfiguration or inability to autodetect hardware properly
such as from using a KVM switch that blocks DDC, or having the
monitor turned off during X server startup, etc.
From the command prompt, running:
redhat-config-xfree86 --reconfig
... on the machine should result in a working video configuration
with ability to use up to 2048x1536, although I don't remember
what resolutions our config tool presents to users off hand, the
X server and radeon video driver can max out the card's
capabilities. All of this is assuming a CRT monitor. DFP panels
may or may not work similarly, don't know as I don't have such
hardware to test with.
Hope this helps.
