By definition, the "vesa" driver, uses the VESA BIOS Extensions present on the video card's ROM BIOS. This allows the X server to set up video modes and manage the video hardware, without actually knowing anything about the specific video card itself. It does not however provide acceleration. It is impossible to provide acceleration for the vesa driver, because the actual code is in the video card's BIOS chip, and not part of the X server. The VESA VBE/AF standard includes accelerator functionality, but to the best of my knowledge, zero actual video cards provide VBE/AF in their BIOSs, and as such, it is impossible to provide any kind of 2D acceleration on any hardware when using the "vesa" driver - so it will _always_ be slow. If anyone is aware of any video hardware that does actually provide VBE/AF support in the built in BIOS, let me know as it wouldn't be too difficult to add VBE/AF support to the "vesa" driver. I seriously doubt that any cards out there exist that support VBE/AF however, so don't hold your breath. >Radeon - This mode is somewhat buggy in XFree86 4.2.

If you are wondering, >here are the settings I used for the display in the file: The Mobility U1 is totally unsupported in 4.2.1 and earlier, which is why it doesn't work. ;o) It is not to my knowledge based on the Radeon 7500 however. If I'm not mistaken it is based on the Radeon 9000. If someone can test the latest XFree86 CVS code (the absolute latest) on a Radeon Mobility U1, and tell me wether or not the native "radeon" driver works or not on it, I'd be more than glad to help troubleshoot and add/fix support for it. Let me know what the output is for the video card: lspci -vvn TTYL -- Mike A.
