Nvidia proprietary driver

ReaperX7 · 08-10-2015, 03:49 AM

Our xorg-server was built to the defaults Enorbet. That's why we have the error in the xorg logs.

Patrick probably didn't know about the switch when he was importing that version of xorg-server. Yes, it needs to be disabled in the standard Slackware release. If primus and bumblebee both detect that stray setting and cause a foul up when launching 3D applications, then it is a problem, but normally it should work without any issues.

Maybe something changed?

Hello everyone!

It requires (or greatly prefers) the Intel driver be installed before the nvidia driver.

Well, what is a intel driver? Integrated videocard runs out of the box, doesn't in? Is it libva-intel-driver that I must install?

Quote:

Additionally it is recommended that you create and add user to the bumblebee group

Done that from the beginning.

Quote:

Plus you need to enable the bumblebeed.service

It is enabled in my rc.local

Quote:

GLX errors should be solved by letting nvidia install mesa et al.

Could you please more thoroughly explain how to do that? I have no idea.

>>>I am still experiencing GLX errors, can't run steam and most of the games.

And to ReaperX7,

Quote:

You can try to reinstall the Nvidia-driver and see if it does help, but if Steam is checking for Xorg, it won't matter what driver you install, as this is not a driver issue, but an issue with the xorg-server directly.

I can walk you through fixing this if you're interested.

I would really appreciate it! Myself I have no idea how to do it.
First of all, I need to get this: http://mirrors.slackware.com/slackwa...1/src/xserver/ , right?

You first need to use an ftp client like gftp to navigate to the Slackware server of your choice. Look for this folder in the ftp navigator:

Code:

http://mirrors.slackware.com/slackware/slackware64-current/source/x/x11/

and have it copy the entire directory to your system.

Afterwards, open directory:

Code:

configure

and look for the xorg-server file. Open it and edit it in the section:

Code:

CFLAGS="$SLKCFLAGS" \
./configure \
  --prefix=/usr \
  --libdir=/usr/lib${LIBDIRSUFFIX} \
  --sysconfdir=/etc \
  --localstatedir=/var \
  --infodir=/usr/info \
  --mandir=/usr/man \
  --disable-static \
  --with-pic \
  --enable-suid-wrapper \
  --with-int10=x86emu \
  --with-default-font-path="${DEF_FONTPATH}" \
  --with-module-dir=/usr/lib${LIBDIRSUFFIX}/xorg/modules \
  --with-os-name="Slackware 14.2" \
  --with-os-vendor="Slackware Linux Project" \
  --with-xkb-path=/etc/X11/xkb \
  --with-xkb-output=/var/lib/xkb \
  $BUILD_SERVERS \
  --build=$ARCH-slackware-linux

to become:

Code:

CFLAGS="$SLKCFLAGS" \
./configure \
  --prefix=/usr \
  --libdir=/usr/lib${LIBDIRSUFFIX} \
  --sysconfdir=/etc \
  --localstatedir=/var \
  --infodir=/usr/info \
  --mandir=/usr/man \
  --disable-static \
  --with-pic \
  --enable-suid-wrapper \
  --with-int10=x86emu \
  --with-default-font-path="${DEF_FONTPATH}" \
  --with-module-dir=/usr/lib${LIBDIRSUFFIX}/xorg/modules \
  --with-os-name="Slackware 14.2" \
  --with-os-vendor="Slackware Linux Project" \
  --with-xkb-path=/etc/X11/xkb \
  --with-xkb-output=/var/lib/xkb \
  --disable-systemd-logind \
  $BUILD_SERVERS \
  --build=$ARCH-slackware-linux

Now go back to the root directory of the x11 directory you copied and run:

Code:

./x11.SlackBuild xorg-server xorg-server

This will rebuild xorg-server according and drop some packages in /tmp when completed. Just use 'upgradepkg --reinstall' on them. Now restart the X server and check the log. You should NOT have any (EE) entries which means systemd-logind support is now gone.

Try running primusrun with your applications and see if it helps. Hopefully it will.

Thanks for the guide!

Nothing happend. Really nothing.

The right command : ./x11.SlackBuild xserver xorg-server

ReaperX7 · 08-10-2015, 07:32 AM

Ah my mistake. Heh... Anyways how did it work?

Not so effective. ^_^

Code:

(EE) xf86OpenConsole Cannot open /dev/tty0 no such file etc.

/dev/tty0 is owned by root
/use/bin/Xorg is owned by root, 755.
Maybe SUID bit needed?

ReaperX7 · 08-10-2015, 07:50 AM

The tty0 node should be created by the system during the boot phase, namely during the /dev mount and starting of udev. It should also be activated for agetty by the entry in /etc/inittab.

Are you logged in as root to test it, or a user account?

Youmu · 08-10-2015, 07:54 AM

As user startx throws above error.
As root everything works.

Inittab wasn't changed since installation of slack. But there is no tty0 line in there.

Youmu · 08-10-2015, 08:20 AM

Actually good news!!!
If startx initiated as root, there is no problem with GLX extensions! Glxinfo works perfectly. Now all remains is to do startx as normal user.
Thanks.

j_v · 08-10-2015, 08:22 AM

Code:

ls -l /usr/bin/Xorg | cut -d' ' -f1,3,4

should output:

Code:

-rwsr-xr-x root root

if not, as root:

Code:

chmod u+s /usr/bin/Xorg
chown root:root /usr/bin/Xorg

EDIT: AFAIK, the x server need to be suid root

e5150 · 08-10-2015, 08:33 AM

I've also recompiled xorg-server, but not with the stock slackbuild. I had to set both Xorg.bin and Xorg.wrap (found in /usr/libexec) suid root. Although the --enable-suid-wrapper option would have me believe that only Xorg.wrap ought to need to be set suid. But I never bothered to dig deeper.

Won't chowning after setting the suid flag void that permission?

Xorg.bin and Xorg.wrap

That helped! Thanks!
Now I am able to run startx as normal user.

=> Everything okay.
But I am still experiencing some problems with glxgears and primusrun:
2. primusrun glxgears

Code:

Xlib:  extension "NV-GLX" missing on display ":8".
Segmentation fault

Thanks a lot!

Ooops, right. Should have done the chown first (not strictly necessary, but I figured the perms are wrong, better reset ownership, too). Thanks.

Although I intend to continue watching this thread and offer suggestions if and when I see something of which I feel certain, but given that I don't have Optimus and still install nVidia proprietary driver generically from runlevel 3 (not a slackpack nor slackbuild) I think I should hang back to avoid confusion with steps and actions that don't apply or miss extras I don't have to contend with.

Example - nvidia's installer searches for conflicting libraries and installs GLX and Mesa that it knows works with that version driver and hardware. It is not known to me if the SBs behave in this manner. I've been installing nvidia's driver this way for over 10 years and excepting choosing newer drivers on old hardware that would not install (and told me why and what to get) I have never had any problems with nvidia drivers and I don't have to wait for someone to build a SlackBuild nor create one myself for nvidia anyway.

Best Wishes for Good Fortune
