[Solved]Almost all set...couple of problems with hardware

[nextekcarl]

I installed Gentoo, emerged kde (couldn't use the GRP packages becuase my CDROM doesn't seem to work except to boot???) and that took at 26 to 28 hours to complete, but [most] all seems to work well now. I have sound working (recompiled the genkernel and added my sound driver and NIC driver to the kernel). I am quite happy with Gentoo, and I know a lot more about my system now. I still have a couple of problems, and after spending many hours trying to figure out how to fix them, I am stuck.

1. I have a Geforce3 Ti 200 agp video card. I have used it with other distros and was able to get the hardware accelleration to work without too much trouble. I have tried emerging both the stable and the unstable nvidia drivers, and when I go to change the setting "nv" to "nvidia" and comment out "Load DRI" in my Xorg file X fails to load. It gives me an error about this driver not being for this chipset. I get the same thing if I try to use the drivers directly from nvidia. The last time I had hardware acceleration working it was with an older kernel (2.4.x) and now I am using 2.6.11-gentoo-r3 and from one of the posts it sounds like that could be a problem, but I can't find anything for sure, I could buy a newer card, but I want to know that that will fix the problem, and that it isn't something else. Any ideas?


2. I have a CDROM drive that works great for installing linux, and booting live cds, but if I try to actually mount it when I have linux running (like to use the GRP package set to install KDE) it usually hard locks the system, and I think it is what made grub-install lock up with kernel panik, but I'm not 100% on that. I did get it installed ok, so I'm not too sure about that. I just saw a message about cd drives being blacklisted and therefore being prevented from setting DMA on the drive, but I have never heard of that before, so I have no idea if that could have anything to do with my problem. I thought DMA was just for quicker transfer anyways, so that may not be my problem. Again, I can buy a new drive, but I want to know that I'm not wasting my money.

Thanks a bunch. Here's my fstab in case that would help for the cdrom question:

# /etc/fstab: static file system information.

# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.

# <fs> <mountpoint> <type> <opts> <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda1 /boot ext2 defaults,noatime 1 2
/dev/hda3 / ext3 noatime 0 1
/dev/hda2 none swap sw 0 0

#/dev/fd0 /mnt/floppy auto noauto 0 0

# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:

none /dev/shm tmpfs nodev,nosuid,noexec 0 0

for the first option, try emerging nvidia-glx, then put glx in the modules section of you xorg.conf. That should get you going on that. You may also try emerging nvidia-settings.

As far as your second problem, no idea. Sorry. Good luck though.

I did that when I did the drivers, I should have said that. I also did "opengl-update nvidia" and modules-update. The I made the changes to xorg and until I change it back to "nv" I can't start X11, startx gives me the error I mentioned, and kdm just gives me a black screen for a second or two and then quits back to the console. Here's my [relevent parts] of xorg.conf:

This is the error I get if I try the above settings (and I checked, I had the nvidia module loaded):

This line was causing all the problems:

It appears that auto in the media type setting in fstab is what was causing the problem with my cd drive. I had to set it to iso9660 and now it seems to be working just fine. The gentoo handbook listed auto as being ok, does anyone know why it would be a problem like this:
