Hi dkilmer, Can you please provide nvidia bug report of your system as soon as issue hit? What desktop env your running xfce, kde, gnome?
I wouldn’t say the problem “hits” so much as “exists from the moment my desktop manager starts”. I’m using Unity in the video, but I have also tried Gnome and xfce. They all have the same basic behavior.
Here’s a link to the output from nvidia-bug-report.sh:
Hi dkilmer and all, Is the Nouveau driver performance is better then nvidia when using dedicated nvidia gpu from SBIOS settings where Intel gpu disabled?
Actually I want to isolate this issue is intel+nvidia+prime OR nvidia+nouveau perf issue?
Also Did you test by adding “Intel” instead of “Modesetting” ? Any perf improvement?
If I turn PRIME off in the BIOS, the performance of the NVIDIA proprietary driver is good (better than nouveau). I haven’t tried it on an external display, but it completely solves the problem on the laptop’s internal display.
So I’d say PRIME is definitely your culprit.
I’m not really sure how I’d choose Intel vs modesetting. I’m just choosing Intel from the NVIDIA Xserver settings, and the performance is fine.
In your /etc/X11/xorg.conf in below section replace Driver “modesetting” with Driver “intel”. I think you need xorg intel driver or package on your system.
Section “Device”
Identifier “intel”
Driver “modesetting”
BusID “PCI:0@0:2:0”
Option “AccelMethod” “None”
EndSection
Section “Device”
Identifier “intel”
Driver “intel”
BusID “PCI:0@0:2:0”
Option “AccelMethod” “None”
EndSection
I’m having trouble evaluating this one. I don’t have an xorg.conf file, but if I generate one with nvidia-xconfig and change modesetting to intel, it gets overwritten every time I boot. If I lock xorg.conf with chattr +i, it doesn’t get overwritten, and the performance is less good than just choosing intel from NVIDIA Xserver settings but not as bad as when I switch to NVIDIA with PRIME enabled. But if I change intel back to modesetting in xorg.conf, the performance stays about the same. It’s only really fast, in other words, if I get rid of xorg.conf altogether and choose Intel.
I’m not even sure that told us anything. I had all kinds of problems just having an xorg.conf file present.
We are tracking this isue in bug 200324356 : linux eu/oem: prime: Sluggish Performance with “NVIDIA (Performance Mode)” and no issue with “Intel (Power Saving Mode)”.
Is there a way to see the status of the bug?
Same problem! Running with
- M2200 Openbox/GNONE/Unity
- Driver: Nvidia 375.66
- Ubuntu 16.04 LTS
- Laptop: Dell Precision 7520
The screen “blacks” out for parts of a second every 10 to 20 seconds.
No clue if this helps at all. I am running in Performance Mode.

If you need something else, let me know.
P. S. 1:
When I run nvidia-settings I get the following terminal output beside the GUI:
** Message: PRIME: No offloading required. Abort
** Message: PRIME: is it supported? no
prime-select query gives back nvidia.
Hi urshof, Can I get nvidia bug report of your system?
I see most of guys are using Dell Precision 7520 . Any other systems are also affected with exact same issue excluding [Lenovo Thinkpad P51 (Kaby Lake Xeon + Quadro M2200)] ?
I already attached the bug report above. I will try it with a new installation of the system today. Dell sells the computer with a preintalled Ubuntu, perhaps they did something wrong during setup.
Hi all,
Our QA need some more info to reproduce this issue:
As of now we are not able to repro this issue on below config
Config:- ( Dell precision tower 7520 + Ubuntu 17.04 Zesty + Quadro M2200 (GM206GL-A) GPU + VideoBIOS: 84.06.76.00.14 + LGD Screen touch panel + Driver 381.22 )
Repro steps attempted:-
Installed Ubuntu 17.04 and disabled nouveau
Install Driver 381.22 from repository which has prime configuration
From BIOS it is set has " Enable switchable graphics "
From Prime config i have selected has “NVIDIA (Performance Mode)”
Performed resizing window , scroll up and down
Here i am not able to see the sluggish performance as reported by User, Not much but with comparison little slow performance is observed in Nvidia mode and with Intel its smooth
Additional Information tested with Nvidia mode:-
Attempted try with Unity, Gnome , Xfce , Mate → No sluggish performance observed
AC-mode → No sluggish performance
DC-mode → Little slow performance
If i change the theme in Mate like " Ambiance" " Traditionalok" + AC mode → Little slow performance
Please provide below details :
- let us know if we are missing something?
- Are you able to see sluggish performance with AC mode or DC-mode?
- Do External 4k monitor is required to repro this issue or only NB can be useful to repro the sluggish performance?
- Did you applied any power related config / modification?
- Were you able to repro with fresh OS ubuntu or did they installed any additional package or desktop environment?
- Any Theme were selected and configured?
- Please request some more video from other users to see the intensity of the sluggish performance issue?
- Using Nvidia Were they able to see the sluggish performance with Bare X?
Hi dkilmer,
- What kind of Desktop environment you are using, What theme has been applied, How did you configured the task menu items which is place bottom of the GUI any package were installed? What desktop Panel you are using - gnome-panel, unity-panel or else ?
The bug report you attach don’t have nvidia prime setup. Can you please configure PRIME and then share nvidia bug report. Also share video showing slowness in the performance mode when selected nvidia.
Hi, Sandip – Are you using the 7520 laptop with the internal 3840x2160 display? I don’t think the 1920x1080 display would have the same problem.
I’m running Unity desktop with the default Ambiance theme. The menu/title bar scaling is set to 2.00 for the internal display. The dock you see in my video is Plank. The application you see scrolling so slowly is Sublime Text.
I have no special power usage setting set.
My installation seems to otherwise be exactly what you have above, except that my video BIOS version is reporting as 84.06.76.00.1c.
Hi Guys, I see this notebook has option “Graphics spec mode” in SBIOS . Hope you are not testing with it and its unchecked always? And power adapter always connected?
That mode doesn’t exist in the SBIOS settings on my Precision 7520. I have an option that says, “Discrete Graphics Controller Direct Output Mode”, which may do the same thing.
It’s unchecked in my settings, which is the reason why I can run my external monitor using the “Intel” option under the Prime settings.
I am also experiencing a similar issue here under Ubuntu 17.04 on a Lenovo P51 with the m2200 and Xeon processor. Is there anything I can help provide you to diagnose this?
External monitor is not working, and when the nvidia card is selected the desktop is choppy with very bad screen tearing.
Neither in my bios. Where should the option “Graphics spec mode” appear? Searched through all of the BIOS (DELL Precision 7520)
We are able to reproduce this issue and dev is investigating it.
I have a ThinkPad P51, same problem.
A workaround is: suspending and then resuming (it works until the next reboot).
