From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.3-2.9.2smp i686) Description of problem: Video card: nVidia Corporation Riva TnT2, 3D Blaster AGX, 32MB Monitor: HP A4033A problem, default boot uses a frame buffer that causes the screen to flicker so bad that reading the screen is out of the question, much less doing an install. reboot, select "nofb" - slightly better. The initial boot gote ok, then X starts, and the flickering is again terrible. reboot, select lowres - this time everything is ok. In all 3 cases, the video card is properly identified as RIVA TNT2, and the monitor is misidentified as UNIDENTIFIED MONITOR I'm wondering out loud here, is there some way to drop into lowres mode without rebooting, if the installer can tell that the user can't read the screen (such as by a timeout, or something)? How reproducible: Always Steps to Reproduce: 1. Boot with the following video card: nVidia Riva TnT2, 3D Blaster AGX, 32MB Actual Results: screen flickers, constantly. unreadable. Expected Results: no flicker. Additional info: Work around is to boot "lowres", but that's not as documented as well as it could be.
This defect considered SHOULD-FIX for Fairfax.
The monitor settings we have selected in the case of a undetected monitor are extremely conservative (equivalent to an IBM XGA display in 1989). It is rare (first report I've heard actually) for it to cause problems. There is no easy way to make X and anaconda switch to a lower resolution once running. You did the proper thing and tried lowres mode, which is what it exists for.
