Optimus Nvidia problems [17.2]

[protondonor]

I've been trying all morning to get Optimus to switch from Intel to Nvidia drivers. Currently, using NVIDIA X Server Settings to change gives a blank error message and there is no system tray icon (as mentioned in the update notes for 17.2) that would allow me to switch drivers. I tried a variety of suggestions that I found, ranging from editing bumblebee configurations (which caused a lot of problems), to reinstalling the drivers (which I've done multiple times, with no real success). I don't currently have bumblebee installed (had to uninstall it earlier; when I finally got it working and switched my graphics to Nvidia, OpenGL wasn't working at all and graphics wouldn't switch back to Intel), but I saw a comment on the forums stating you don't need it anymore in 17.2. Is that true? How can I get my computer to switch between Intel and Nvidia drivers, and get both of them to work properly?

inxi -Fxs doesn't currently show that I have an Nvidia graphics card (745) on my system, and modprobe nvidia reports "FATAL: Module nvidia not found":

modprobe nvidia reports "FATAL: Module nvidia not found"

i nvidia-346 - NVIDIA binary driver - version 346.82
i nvidia-prime - Tools to enable NVIDIA's Prime

Strange since nvidia driver is installed. Try to reinstall driver this way, plus LM nvidia applet

Code: Select all

sudo apt-get install --reinstall nvidia-346 nvidia-prime nvidia-settings nvidia-prime-applet

Installation should report no error message. Then reboot and try to select nvidia card through apllet or Nvidia X Server Settings.

[protondonor]

Installation reported an error:

On rebooting, I cannot select the NVIDIA graphics card, but the icon for selecting graphics card does appear in the system tray (as a small quote bubble with a red X inside and a red background; I would post a screenshot but print screen is not currently working). Once again the NVIDIA settings tool gives a blank error message when trying to switch to NVIDIA.

[Laurent85]

/usr/sbin/dkms: line 81: patch: command not found

Installation failed. For some reasons patch command is missing, reinstall patch package

Code: Select all

sudo apt-get install --reinstall patch

Then start over nvidia packages reinstall

Code: Select all

sudo apt-get install --reinstall nvidia-346 nvidia-prime nvidia-settings nvidia-prime-applet

Any errors reported ?
Reboot.

[protondonor]

No errors reported, but on rebooting, the results are the same.

modprobe nvidia still reports "FATAL: Module nvidia not found."

It appears that your inability to switch GPUs problem is seen often on systems with Optimus technology. I'm wondering if it's related to the bug report on this web page:
https://bugs.launchpad.net/ubuntu/+sour ... ug/1310023

Could you post some information. Use these commands in the Terminal:

Code: Select all

1. cat /var/log/gpu-manager.log
2. dmesg | egrep "bbswitch|nvidia"
3. ls /usr/share/nvidia-prime
4. cat /sys/class/dmi/id/sys_vendor
5. cat /sys/class/dmi/id/product_name

6. Open the Xorg.0.log file with this command and post the contents:

Code: Select all

gedit /var/log/Xorg.0.log

If you have problems posting that long file, then upload it to pastebin.com by using this command:

Code: Select all

pastebin /var/log/Xorg.0.log

Post the URL link that displays in the Terminal window.

[roblm]

Driver Manager claims I'm using nvidia-340-updates so not sure why xorg logs don't match that.

Driver Manager shows the nvidia-340 driver was installed but it is currently not the loaded driver. As these lines from the Xorg.0.log file show,
as the Xorg X Server is starting, it initially tries to load 6 different graphic driver modules, but then all but 2 of them are unloaded:

Code: Select all

[    36.741] (II) LoadModule: "intel"
[    36.895] (II) LoadModule: "nvidia"
[    36.915] (WW) Warning, couldn't open module nvidia
[    36.915] (II) UnloadModule: "nvidia"
[    36.915] (II) LoadModule: "nouveau"
[    37.082] (II) LoadModule: "fbdev"
[    37.132] (II) LoadModule: "vesa"
[    37.178] (II) LoadModule: "modesetting"
[    37.178] (II) UnloadModule: "modesetting"
[    37.178] (II) UnloadModule: "fbdev"
[    38.366] (II) UnloadModule: "vesa"

The results from using the commands shows that the nvidia kernel module (nvidia_346.ko) was built successfully but the bbswitch is not loaded, which
will prevent hybrid graphics switching from working. The bug report page says:

"On some systems bbswitch requires the "skip_optimus_dsm=1" option in order to load properly."

But it doesn't explain how to use it. Incredibly, I could only find one web page that gives an explanation. It said to place the option (also called a quirk), in
/usr/share/nvidia-prime/prime-quirks, using this format:

Code: Select all

"dmi product version" "bbswitch options"

And gives this example for a Lenovo Thinkpad, model T410:

Code: Select all

"ThinkPad T410" "skip_optimus_dsm=1"

Open the prime-quirks file with this command:

Code: Select all

gksudo gedit /usr/share/nvidia-prime/prime-quirks

So I guess in your case the line would read:

Code: Select all

"ASUSTeK Q550LF" "skip_optimus_dsm=1"

But usually the name ASUS is used, so the line may be this:

Code: Select all

"ASUS Q550LF" "skip_optimus_dsm=1"

Reboot.
The report says that the bug was fixed in the package nvidia-prime - 0.6.6 (read post #48), but you're using version 0.6.2. I don't know if the newer version is
available through the Update Manager.

From looking at the log files, your problem doesn't appear to be exactly the same as the other users in that bug report. If that method fails, then try the other method
suggested in post #51, by using these commands and rebooting:

Code: Select all

sudo update-alternatives --config x86_64-linux-gnu_gl_conf
sudo ldconfig -n
sudo update-initramfs -u

When using the first command, there may be displayed a list of choices, such as shown below:

Code: Select all

Selection Path Priority Status
------------------------------------------------------------
  0 /usr/lib/nvidia-331/ld.so.conf 8604 auto mode
  1 /usr/lib/nvidia-331-prime/ld.so.conf 8603 manual mode
  2 /usr/lib/nvidia-331/ld.so.conf 8604 manual mode
* 3 /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf 500 manual mode

Press enter to keep the current choice[*], or type selection number:

Try selections 0, 1 and 2, which list nvidia, not 3, which lists mesa.

[protondonor]

Tried selection 0, I can activate NVIDIA driver now but OpenGL does not seem to be working:

Code: Select all

~ $ glxgears
Xlib:  extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

[roblm]

Did you Log out and back in after changing to the Nvidia GPU?

Did you try adding the "skip_optimus_dsm=1" option" to the prime-quirks file and is it still being used?

Use these commands:

Code: Select all

1. sudo cat /proc/acpi/bbswitch
2. sudo prime-select nvidia
3. cat /var/log/Xorg.0.log | egrep -i "nvidia|nouveau"
4. dmesg | egrep -i "bbswitch|nvidia"
5. gedit /var/log/gpu-manager.log

[protondonor]

I did log out and back in after changing to NVIDIA. I also switched back to Intel (so I could use things that require OpenGL) then back to NVIDIA the same way, which didn't solve the problem. Both options with "ASUSTek" and "ASUS" are in prime-quirks.

Here are the results of those commands:

Then reboot. If there's no change, then remove the two lines that were added to the prime-quirks file and then use these commands again and reboot:

Code: Select all

sudo update-alternatives --config x86_64-linux-gnu_gl_conf
sudo ldconfig -n

From looking at the output of using this command:
ls -l /usr/lib/x86_64-linux-gnu/mesa/

There appears to be a misconfiguration. Both libGL.so and libGL.so.1 are linked to libGL.so.1.2.0

-rw-r--r-- 1 root root 31 Mar 11 17:47 ld.so.conf
lrwxrwxrwx 1 root root 14 Mar 11 17:47 libGL.so -> libGL.so.1.2.0
lrwxrwxrwx 1 root root 14 Mar 11 17:47 libGL.so.1 -> libGL.so.1.2.0
-rw-r--r-- 1 root root 413968 Mar 11 17:47 libGL.so.1.2.0

I think libGL.so should not be there, but before I have you remove that file, I want to check some other Nvidia driver files that should have been installed and if the
correct symbolic links to some of these files were created. This procedure is recommended by Nvidia for unresolved driver installation problems and discussed in the
NVIDIA Accelerated Linux Graphics Driver README and Installation Guide, Chapter 5 - Listing of Installed Components, on THIS WEB PAGE:

EDITED 9-5-15: I asked another forum user who had a system with Optimus technology to see if the libGL.so link was present on his system, and it was not. So I
told protondonor to remove that link, but it did not solve his problem. Also, all the output from using the commands below did not show any other misconfiguration.

Would you post the output of these commands:
