nvidia legacy cards

Post by mikefox7 » Thu Mar 05, 2015 21:40

Hello Sabayon users

I need help regarding my "old" nvidia 9500 GT video card.
Since nvidia kicked out support for those older cards, it's impossible for me to boot any of the new Sabayon-ISOs.

I tried several different bootparams, but had no success at all.

I hope that anyone could help me with this issue - please.

Regards

I think you should just need to downgrade to the 340 driver, instead of using the 346 driver.

edit /etc/portage/package.mask/00-sabayon.package.mask adding these lines at the end

Code: Select all

>=x11-drivers/nvidia-drivers-341.0
>=x11-drivers/nvidia-userspace-341.0
save file and

Code: Select all

equo update --force
Make sure that is installing nvidia-userspace-340 and nvidia-drivers-340

Then:

Get your video GID from this:

Code: Select all

$ getent video sys | cut -d: -f3
Edit /etc/modprobe.d/nvidia.conf and replace VIDEOGID with the number returned as your video GID. You'll have entry that looks something like: NVreg_DeviceFileGID=33


Then reboot.

Hi Stupot

Thanks for your description to downgrade the video driver in an installed system.
But my problem is, that I can't do a fresh install with the new ISOs, all of them using the newest video driver.
Joost told me to use the bootparameter: modprobe.blacklist=nvidia.
This does not really help, because when the boot process is finished, the desktop shows up in an ugly resolution (I only tried xfce) and the worst: doubleclicking the install icon does not open the installer. Then I tried to invoke liveinst in the terminal, but no success.
So for the time being my only chance is to use an old ISO (14.12). Then I install xf86-video-nouveau, set opengl to xorg-X11, comment out the blacklisted nouveau, delete xorg.conf, uninstall the nvidia driver and userspace, and reboot.
Apart from having to do a lot of updates and change to a newer kernel, it's very time consuming.

I think, over the years, nvidia more and more fails to act user friendly.

hmm, the installer not working is definitely not expected.

Doing an upgrade from an old ISO, you wouldn't have to do all that. After you do the upgrade (but before rebooting) just follow my post above and you should be set. No need to switch from nvidia to nouveau and back to nvidia.

I agree though, it definitely seems like a lot of hassle. nvidia's drivers have been a sore spot every now and again, but we all use them because they are great when they work.

within the live-dvd., you can switch to a TTY, right? (terminal)
Simply revert the drivers by uninstalling the current installed nvidia-driver and userspace:
and install the 340 series,
including it's corresponding userspace:

ctrl+alt+F1
killall xdm (or whatever Display-manager in use)

Code: Select all

equo query installed nvidia-drivers nvidia-userspace | xargs equo remove -a

Code: Select all

equo i nvidia-drivers-340.76#`uname -r` -a;equo i nvidia-userspace-340.76 -a
and restart xdm (or whatever Display-manager in use)

The 340 series is indeed the latest driver your card supports...
You could also try the boot-parameter: xdriver=nouveau
That way you force Xorg to use the nouveau-drivers.

Hi, I am having a similar issue trying to do a fresh install on the current Sabayon release the iso boots however when I try and install all I get is a terminal. I have tried "modprobe.blacklist=nvidia" same result, I have also tried "xdriver=vesa" same result. I have even tried the two together still no joy. My Laptop is an Alienware M9700 with Nvidia GTX 7950. Xubuntu, Arch etc install fine.

Thanks

Adam

I have in mind that only the drivers of the 340 series works, but.... Nouveau seems to work with these old cards.

My cards use the 304 series drivers, which are in the drivers folder in the iso but I can't get nouveau or Nvidia 304 to load. Result: unable to install
