Website Theme Flickering in Chrome

This website – – flickers when you scroll down in Chrome. I get this issue at home and in the office, and unofortunately clients are starting to report the issue. If I switch over to another theme, the flickering goes away. Any idea on a fix for this?

Ubuntu/Linux Mint/Fedora/Manjaro laptop screen flickering with intel graphics

I installed Linux Mint (17 more or less) on a Dell Inspiron 15 Series 7000 i7 Skylake and it worked beautifully for a while. After some OS update (before LM 18) a flicker started to show up.

I read this is a common problem. I’ve tried several workarounds:

  • I’ve been playing with the 20-intel.conf file
  • I’ve added the i915.enable_rc6=0 option to grub on startup
  • I’ve removed the xserver-xorg-video-intel

None of them seems to work. The only option that really works has been to disable the graphic card (entering into LM rendering mode, or through an option in the 20-intel.conf file), but the laptop gets too warm.

And as the title suggests, I’ve tried other distros, even not related to Ubuntu, as Fedora and Manjaro. All of them (including Ubuntu) have shown the same misbehavior.

In my laptop I also have LM Xfce 17.3 in one partition. It’s running the 4.4.0-148-generic kernel, and it does not show such misbehaviour. It makes me think that the problem is not the hardware, but the drivers.

In this image (LM 19.2, 4.15.0-62-generic kernel) you’ll see what I’m talking about. The laptop is unusable under these circumstances.

Any more ideas are appreciated. Thank you in advanced!!

Screen flickering in Ubuntu 18.04.3 LTS

Here You can see too much flickering of the screen. Previously, I had ubuntu 18.10. The screen flickering was not too much, it was only occasional but in 18.04.3 it is increasing day by day. I couldn’t find any concrete solution to solve this problem.

The problem is not in hardware because in the bootloader menu screen doesn’t flicker.

I tried using both Intel® HD Graphics 520 (Skylake GT2) and GeForce 940MX/PCIe/SSE2 Graphics.

Screen flickering while using Nvidia is more as compared to Intel.

I’m also using an external monitor which works totally fine without any flickering.

Screen flickering in Ubuntu 16.04.lts

Recently I am having a problem of flickering screen on my Lenovo laptop where I have installed ubuntu 16.04 . It had also happened a couple of months ago, but was fixed automatically the next day after I connected my laptop to external monitor through HDMI where just mouse was flickering and same thing happened to my laptop screen the next day for a while and was fixed automatically. But the problem is now happening consistantly and is not solved. What can I do for that ?

External screen flickering at native resolution, but not lower resolution, and only in GUI, not console

I have a slightly older HP ProBook Laptop with integrated Intel graphics running Ubuntu 18.04 on kernel 4.19.0 and the external screen (DisplayPort connection) gets tearing and then goes dark for a second and then comes back. It keeps doing this over and over again and it’s impossible to do any work on it. Things that stop this from happening:

  • Lowering the resolution from 1920×1080 to 1600×900
  • Switching to console mode

This issue does not affect the integrated display.

Things that I have tried that have not had any effect:

  • Increasing the amount of video memory in the BIOS
  • Setting vm.swappiness=15 in /etc/sysctl.conf (from default of 60)
  • Installing and upgrading xserver-xorg-video-intel package
  • Trying different environments (same problem with Unity, Wayland, Gnome, etc.)
  • Plugging the monitor directly into the laptop or via docking station
  • Swapping out monitors entirely
  • Adding "TearFree" "true" to the /etc/X11/xorg.conf file

Any ideas would be greatly appreciated.

screen flickering, turning off, 18.10 Intel

I recently moved my work computer home and hooked it to new monitors. One monitor works perfectly, the other (an AOC monitor connected via displayport) flickers and tears occasionally, and then will put itself to sleep and I have to disconnect/reconnect it to the computer to wake it up.

I never had this problem previously with other Dell monitors at the office. I had the problem with 18.04 so tried updating to 18.10 and the problem persists. I’ve also tried changing the refresh rate to no avail.

This is the output of xrandr:

And calling lspci | grep VGA gives:

I’m stumped. Any suggestions welcome.

Screen Flickering [Nvidia optimus, Ubuntu 19.04]

I’ve a Dell 5480 laptop with Intel HD 520 & GeForce 930MX (optimus).

Whenever I use the Nvidia card, the screen flickers randomly. When I switch to intel:

sudo prime-select intel sudo reboot 

It works fine, no flickering.

Weird behavior: When using the Nvidia card, If I run a youtube video, it stops flickering until the video ends.

Sys specs:
Ubuntu 19.04
Intel HD 520 (integrated)
Nvidia 930MX (dedicated)

Swtiching using prime-select.
/etc/X11/xorg.conf doesn’t exist

Any ideas?

Thanks in advance!

Been getting lots of flickering, black bars/boxes and other visual glitches when moving windows and stuff

so I’ve never used a Linux distro before and so this is my first time really digging into things and I’ve mostly been able to figure things out for any other problems or questions I’ve had through just searching online, but this problem seems to be eluding me…

So first of all, let me list what I’m using, and what my specs are.

I’m using Kubuntu 19.04 (64 bit) on my 7-9 year old gaming laptop (I know, I really need to upgrade). My laptop has a GTX 560M GPU (I’m using the latest 390.116 legacy NVIDIA driver), an Intel i7-2670QM CPU and I also have 16GB of RAM. I also have a separate monitor hooked up via HDMI to my laptop and am using both the monitor and my laptop’s screen.

Now, here’s a screenshot of one of the common things that is happening: weird graphical glitch

I’m also experiencing lots of screen flickering when I open up a new window or program, or even just when a dialog box opens up. Clicking out of the new window and then back into it or moving it over to the other screen and then back to the other seems to stop the flickering, but then it just happens again when a new window, program or dialog box opens up. I should note that it’s not always the full screen that flickers, sometimes it’s like 5/6ths of the screen or a little less, and sometimes it’s both screens as well.

I’ve tried a few different things, but nothing has really even put a dent into this problem. I’m really just hoping someone has an idea of what’s going on, and they’re able to tell me what I’ve gotta do.

Thanks so much! 🙂
