Right click menu flickers and gone

If i change the compositor now, do i need to log out or restart or suspend or anything to see the effect ? or is it when i clicked “apply” it is effective straight away ?

If memory serves me, I think just hitting ‘Apply’ changes it. you will see a flicker.

Use a USB2 port on the motherboard. It will be black if you look at it not blue. Same applies for a laptop. You make so many posts I can’t keep up :sweat_smile:

Also, are you using Nvidia by chance, and/or, proprietary drivers?

Sorry, not that i want to post… I just want to get my work done… but when my computer is so annoying to use, i can’t help it but ask for help
Btw, i am using usb with black color in it (USB2.0) for my mouse.

Did you try the blue one?

Sorry, took so long to reply (i need to read up to know what command to enter to get what you want to know).
May i know what does this output of this command shows ?
Am i using Nvidia or Integrated Graphic controller ?

Yes, just tried. Same, in fact it looks worst , i have to click more time to get it.
As a person posted on internet regarding this issue:
" Some time after right clicked, hold the right button do not let go, the menu will be there ; but if click and let go the button, the menu will be gone. "
Also, after several times of right click menu flicker and gone, eventually, the menu will be there, not “appears and gone” anymore, until i click on something else…
That’s why it is hard to describe, because it is totally random.

You have a hybrid system, both Intel and Nvidia GPUs. I am not really familiar with the hybrid setup, I always run pure Nivida with proprietary graphics, but one option to try is toggling off ‘Sync to VBlank’. Usually I find this in the Nvidia Settings app which you would have if running proprietary graphics. See if you have it and look for that option under the OpenGL Settings tab.

The above is if you are using Nivida, but if you are using your Intel GPU and getting screen tearing, then this might be a solution;

I don’t know if this will provide you any info or not.

That is just an info app. You can’t make any changes with that. First type in the following in terminal to see which gpu is active. The one with ‘controller’ at the end will be the active one.

lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA

So you must be running a laptop with hybrid graphics. Intel i915 and Nvidia GeForce 940 Mobile. It looks to me like you are basically running on Intel graphics and nouveau is loaded for the Nvidia although it doesn’t look like you have the hybrid graphics set up to switch back and forth. Do you get any other graphics anomalies of the flickering besides the right click?

$ lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller])

It just show intel control. Didn’t show nvidia controller. I wonder what does that mean ?

No, no other glitches nor flicker ever noticed.
Darn it, so my laptop does not have dedicated nvidia 940m… got tricked… i thought it is a dedicated graphic laptop.
Do you think it could be dual graphic card (nvidia and onboard intel) ? So the os can be set to choose one graphic card that work best ? :upside_down_face:

You should try the method above that @RodneyCK posted and see if it solves the problem first.

Then that means you using strickly open-sourse Intel GPU drivers. You would have to reconfigure your setup and again, I am not the one to ask about hybrid setups. I would refer you to;

Here for hybrid setup or look on the forum.

Here for strictly Nvidia driver setup.

I think properly setting up your drivers will fix your flicker issue.

@andrew_ysk
If you want to run a test. Show the output of this.

nvidia-installer-dkms -b -t

What can be learn from this log ?
I have no idea what i am looking at. Just know it is a test installation of Nvidia driver…

So it looks like the test runs okay for installing the nvidia-dkms with bumblebee. But I’m not an expert on the hybrid set up. So you can have it with just bumblebee or you can set it up with optimus which I think most do. I think you are on KDE plasma? So this was just a test install to see if there are any errors. There are other steps first of all to install it. Then if that goes okay then there are more steps to install optimus. My concern is you don’t have enough experience and if it goes wrong? Everything doesn’t always go right so I need to think about a few things. I’m also not sure how you want to use the laptop. Do you understand the hybrid graphics and it’s use and purpose? You should read up on it a bit. The idea is to be able to switch back & forth between Nvidia and intel. Nvidia is better graphics all around & for gaming but uses more power. Just giving you information for now.
