here's the log file with the X config file set to 32M video ram
Created attachment 95811 [details]
here's the log file for the X config file that fedora core 1 gives me
this X config file only does 1024x768.
the other one does 1280x1024.
the only significant diffs between the X config files is the VideoRam option,
and the list of screen sizes.
-(**) NV(0): VideoRAM: 32768 kBytes +(--) NV(0): VideoRAM: 32768 kBytes Both of these log files show that 32Mb of video RAM is being used. Have you attached the wrong log file? Please make sure you're using a config file with no VideoRAM option and attach the log file from that. If the video adaptor gets detected as 32Mb of RAM properly, and you are having a problem with video modes still, then there is a different bug in the driver of some sort, and I can investigate that also. Shouldn't be hard to find I don't believe. Thanks in advance. Late Friday afternoon, when everyone else is heading to the pub, is a really bad time to file bug reports. You are in a rush to get away, and despite trying to be meticulous and responsive to a personal request for info, you ignore little things subliminally niggling at your attention. To wit: I popped in a working X config file from a previous install (anaconda? from rh9?) where I had to tell the install that I had 32M videoram, and not the mere 4M that it got from somewhere that wasn't an actual correct probe of the hardware. There were actually TWO (2) significant differences between the two X config files: the first was the adding of a VideoRam option. The second was the specification of a "1280x1024" screen resolution. It was the second that was the important thing. The VideoRam option was superfluous, the driver already knew that the card had 32M. But RH7.3, RH8, RH9, taroon beta2 installs all think the card has 4M videoram, and gave me the option to manually specify 32M videoram, permitting me to ask for 1280x1024 screen resolution. The fedora core/1 installation doesn't even ask, it just bores ahead hardcoding the 1024x768 screen resolution into the X config that the fictitious 4M videoram would give me, and gives me no GUI way out of that misconfiguration. So two things are broken: (1) anaconda or whatever is claiming that this card has only 4M videoram. (2) there appears to be no way to get the running system to reprobe for the resolutions. Where do these two bugs need to be refiled? There is no known way to autodetect the proper amount of video memory on Nvidia Riva TNT hardware, so the X video driver assumes 4Mb, as all Riva TNT have at least 4Mb of RAM and will thus work. If you have greater than 4Mb, you have to manually configure the X server to tell it that. I've been unable to acquire any technical information from Nvidia or elsewhere on how to detect memory on this hardware, but that has not turned up anything. As the hardware gets older and older, it seems aparent that this problem will never be resolved without the help of Nvidia. I'm going to close this as "WONTFIX", as there's nothing that can really be done about it at Red Hat, however you can file a bug report upstream at http://bugs.freedesktop.org against the "xorg" product, "Driver/nv" component if you'd like to have it tracked upstream. Perhaps someone from Nvidia can shed some light on the issue in the upstream bugzilla. Setting status to "WONTFIX" |
