The PowerVR Kyro hardware is unsupported by Red Hat as there is no open source native driver for it. The "vesa" driver which you are using, uses the video card BIOS VBE routines to set up video modes and control the display. Problems with VT switching when using the "vesa" driver, are almost certainly due to bugs in the video card BIOS itself, or in the kernel console locking code. In the case of the kernel, it would generally occur with all video hardware and be a commonly reported problem. Whereas in the BIOS case it would likely due to the BIOS not saving and/or restoring video registers properly. This would thus not be an XFree86 bug, and not fixable. If it were a vesa driver bug, which is very unlikely, it should be easily reproduceable on any video card using the "vesa" driver, however I can't reproduce it on several cards I just tested locally, including a Kyro II made by VideoLogic. That is probably indicative more of a bug in your card's BIOS which is not present in BIOS of the card I have. Here are 2 suggestions to work around this problem: 1) Try using kernel framebuffer support or 2) Try using PowerVR's binary only driver (unsupported) Hope this helps. |
