Nvidia-kernel and High Memory support

[paranode]

Hi all,

I have a GeForce 4 MX 440 video card here in my computer at work. It's just a regular Pentium 4 2GHz desktop (no SMP or anything out of the ordinary). I am currently using gentoo-sources-r5. I had everything working great with the video card, nvidia-kernel and nvidia-glx were doing their job and 3D was good. However, I got some new memory in and so I decided to recompile the kernel with High Memory support (the 4G option, I have ~1.2GB total). This broke the nvidia driver, and when I modprobe it I get some dependency errors (something like khighmem, I forgot them). Recompiling the nvidia drivers doesn't help. Also the NTFS module gives a dependency error but that's less important. However, if I turn it back off and recompile everything's fine. It will also work with the nv driver with high memory enabled, but I'd prefer the nvidia driver. This problem is 100% reproducible.

I've read all through this thread and nothing helps. Is there anyone out there who uses nvidia-kernel/glx and the HIGHMEM option in their kernel? Please let me know what kernel you are using, and maybe I will need to see your .config if that's alright. Thanks!

Switching to ac-sources seems to have solved the problem, but now my framebuffer console gets garbled when text scrolls up the screen. I'll have to take a look into this, and I'll probably file a bug report with gentoo-sources.

[edit] I fixed the framebuffer problem by removing the ywrap switch in my Grub kernel boot line. Sweet. [/edit]

Hi I ran into the same problem.
Try and update you portage tree (emerge sync).
Make sure you have at least these versions
media-video/nvidia-kernel-1.0.4363-r2 (emerge -vp nvidia-kernel)
media-video/nvidia-glx-1.0.4363 (emerge -vp nvidiay-glx)

Save your linux .config somewhere safe (cp /usr/src/linux/.config ~)
do a fresh make (make mrproper or emerge gentoo-sources-2.4.20-r5)
copy config back to linux directory (cp ~/.config /usr/src/linux)
remove your modules directory (rm -rf /lib/modules/2.4.20-gentoo-r5/) I am not sure that this is alwasy needed
rebuild kernel (make dep bzImage modules modules_install)
boot new kernel and emerge nvidia-kernel


Hope this helps
