nVidia graphics glitch 18.3 all DE

[Sgthawker]

I have a graphics glitch on all 4 DE for Mint 18.3 with my nVidia GTX 1060 graphics on my Asus ROG Strix GL502VMK laptop.

Here is my inxi for Cinnamon:

Here is a Picture from KDE.

I am not sure what label to give the uneven gradients in the image therefore I am unsure how to google an answer to the issue. I took a screenshot and looked at it on my desktop and it looks normal, it is just the actual display on the laptop screen that shows the glitch, so the above pic is a photo taken with my camera. Thanks for any responses to help me fix this issue. Happy Holidays!

Hi Sgthawker,

I believe the phenomenon you're seeing is called posterization or banding and happens when the bit depth isn't enough to display all colors or shades so you see steps from one shade/color to the next.

Have you installed the proprietary nvidia driver via Driver Manager yet?

EDIT: Yes you have the driver installed, what does Nvidia X Server Settings - X Screen 0 - Depth say?

Hi Sgthawker,

I believe the phenomenon you're seeing is called posterization or banding and happens when the bit depth isn't enough to display all colors or shades so you see steps from one shade/color to the next.
EDIT: Yes you have the driver installed, what does Nvidia X Server Settings - X Screen 0 - Depth say?

Thanks for your reply.

Depth is 24.

[greerd]

I'm not sure whats going on, 24 bit depth should not be showing banding like that. Are there BIOS settings for this?

To see if Mint detects your monitor correctly you can run

Code: Select all

xrandr --verbose

then scroll down to the connector type that shows connected, in that section your should see what the system has set including an EDID blob of hex data. (edid is your displays data)

The easiest way I've found to view/decode edid data is to install an app from the repos sudo apt install read-edid which is comprised of two apps, get-edid and parse-edid. These two, in combination, will display in human readable form, the edid data.

Code: Select all

sudo get-edid | parse-edid

If its not the bit depth, and your xrandr and edid look ok, it could be the color profile you're using.

If dual booting with Win 10 and the display is not banding in Windows, you could try copying the display profile from Windows to Mint, the profile should be a .csm or .icc file. I'm not sure where it is in Windows but if you find it, copy to ~/.local/share/icc/ in Mint, then run Menu - Preferences - Colour Profile Viewer and Add then choose the new profile.

Edid seemed to output the above and then had a flashing cursor at the bottom but seemed to do nothing else.

Anything helpful here?

[greerd]

It could be that your LapTop is too new, the xrandr output shows the EDID blob but no resolution options, for example mine shows

Your default resolution shows 1920 x 1080 @ 60.02 Hz (from your inxi output) so the resolution looks good. We could try adding a Modeline to xrandr but I don't know if that'll help (since your resolution looks ok). If you want to try, the cvt output for 1920 1080 60.02 is
Modeline "1920x1080_60.02" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
You can use this link to do this, substituting the modeline from the link with the one above and substituting VGA-0 with DP-2.

Have you tried copying your windows display profile?

Hopefully some else will jump in here with an idea or two!

[Sgthawker]

Thanks for your suggestions. I removed the Win 10 HDD and installed the Nvme and SSD with only linux installs. I would have to reinstall the HDD to look for that info there, so that will take some time.

@greerd

If dual booting with Win 10 and the display is not banding in Windows, you could try copying the display profile from Windows to Mint, the profile should be a .csm or .icc file. I'm not sure where it is in Windows but if you find it, copy to ~/.local/share/icc/ in Mint, then run Menu - Preferences - Colour Profile Viewer and Add then choose the new profile.

I finally got a chance to install the Win 10 HDD, and of course the laptop would not boot from the HDD. I then booted a Knoppix USB stick and booting from it I found my color profile at C:\Windows\System32\spool\drivers\color\*.icm. I don't know if an .icm file will work the same as an .icc file but it did not work per your instructions to copy it to the above directory and choose the profile viewer and add & select it. Any more options?

Unfortunately no, I have no more, hopefully some else will cut in. But I do have some questions. How does the monitor look when using windows or knopix? Did the .icm load in Color Profile Viewer? (if not you can rename it to .icc and try)

All of my Mint unit displays are EDID version 1.3 and don't display the bits per primary color channel so I can't compare but yours says 6 bit per channel which adds up to 18 bits per pixel or 18 bit depth, not 24 bit. See here for more info.

I don't know if your monitor only supports 18 bit depth or your edid isn't being read correctly, but I suspect the later. I don't know what you can do about this, sorry I couldn't be of more help.

Unfortunately no, I have no more, hopefully some else will cut in. But I do have some questions. How does the monitor look when using windows or knopix? Did the .icm load in Color Profile Viewer? (if not you can rename it to .icc and try)

The image is fine with the Linux Mint USB sticks for all 4 DE and the Knoppix USB looks fine as well. I don't even remember when it was under win 10 as I don't think I even booted with it, just replaced the HDD and installed linux ( I just kept the original "in case" in it's factory state).

It was the first time I used the Profile viewer, I am not sure what to have expected, but I didn't see the name of the .icm file as it was copied to the indicated folder as a choice to be selected.

Thanks for your input!

Pass a bus number as an option to this program to go only for that one.

Do you see anything in this nouveau driver that may help with settings for the nVidia driver?

[greerd]

The live version xrandr and edid outputs look much better, I don't know why the installed version doesn't show the same.

Do you recall if the issue was present before you installed the nvidia driver? Your first inxi output shows nvidia 384.90 which doesn't exist in my Driver Manager (mine show 384.98) Also you could try the newest driver (387.34)

If that doesn't help, if it was me, I'd backup any important stuff and do a reinstall.
