I’ve been having this really frustrating issue with my Ubuntu 22.04.2 system, and I’m hoping someone out there can help me out. Lately, my screen has been flickering like crazy, and there are these annoying glitches that make it pretty much impossible to get anything done. It’s like I’m living in a strobe light, and it’s driving me up the wall.
At first, I thought maybe it was just my hardware acting up. I started by checking the connections and adjusting the screen settings, but nothing has really changed. I even tried switching out my cables and plugging it into a different monitor to see if that made a difference, but nope—still flickering and glitching. I’ve read a bunch of forums, and some people mention it could be a driver issue, but I’ve never really tampered with graphics drivers before. I’m using an NVIDIA graphics card, so there’s that.
I’ve seen discussions about how certain driver versions can cause conflicts or stability issues with Ubuntu, and I’m wondering if that might be the culprit here. If any NVIDIA users out there have had similar problems, could you share what worked for you? Are there specific drivers you installed or settings you tweaked to get things running smoothly again?
Also, I’m a bit wary about trying to uninstall or reinstall anything since I don’t want to mess up my system even more. I’ve already tried some basic settings adjustments in the display manager, but I think I need some deeper troubleshooting steps.
Has anyone gone through this ordeal and found effective solutions? Is there a particular command I should run in the terminal to check for potential issues with the driver or the graphics settings? Or maybe I should be changing some configurations in the NVIDIA settings panel? Any tips would be greatly appreciated! I’m really hoping to avoid a complete reinstall since I’ve put a lot of time into setting this up just how I like it. Thanks in advance for any help!
Screen Flickering on Ubuntu 22.04.2 with NVIDIA Graphics Card
It sounds super frustrating dealing with that flickering screen! Here are a few things you can try:
1. Check Your Driver Version
Since you mentioned you’re using an NVIDIA card, the first thing to check is which driver version you have. You can do this by running:
This will show you the current driver version. Sometimes newer versions can have bugs, so if you’re using a newer driver, try rolling back to the last stable driver.
2. Install or Switch to a Different Driver
You can manage NVIDIA drivers using the terminal. To see available drivers, run:
Then you can install a recommended driver like this:
This will install the recommended driver for you. If you want to install a specific version, you could run:
(replace “xxx” with the driver version)
3. Check NVIDIA Settings
After installing the drivers, you should check the NVIDIA settings. Launch it by running:
In there, look for options related to screen refresh rates and sync. Sometimes, adjusting these settings can help with flickering.
4. Xorg Configuration
If nothing else works, you might want to create or edit your Xorg configuration. It’s usually found at:
You might want to specify your GPU settings here, but be careful! Messing with this file can lead to a black screen if done incorrectly.
5. Safe Mode
If your screen flickering makes it hard to navigate, try booting into recovery mode. You can access recovery mode by holding down the Shift key during boot, then selecting “Recovery mode” in the GRUB menu. From there, you can use the root prompt to make changes.
6. Backup Your Settings
Before you dive into any big changes, it’s a good idea to back up your important files and configurations. That way you can restore them if something goes wrong!
Good luck! Hopefully, these can help settle your screen down from that strobe light effect. Don’t hesitate to reach out again if you run into more issues!
If your screen flickering issues on Ubuntu 22.04.2 stem from the NVIDIA graphics drivers, troubleshooting the driver settings can be pivotal. Begin by ensuring you have the latest proprietary NVIDIA drivers installed, as these often resolve compatibility issues. You can check the available drivers by opening a terminal and executing the command
ubuntu-drivers devices. This will list the recommended driver for your system. To install the recommended driver, usesudo ubuntu-drivers autoinstall, and reboot your system afterward. Make sure you completely remove previous drivers that may have conflicts by usingsudo apt-get purge nvidia*before installing new ones.If updating or changing the drivers doesn’t resolve the issue, delve into the NVIDIA settings panel, where you can tweak configurations related to your display. Launch it via the terminal with
nvidia-settings. Adjusting the refresh rate or disabling certain visual effects can sometimes alleviate flickering. Additionally, check your X configuration file at/etc/X11/xorg.confto ensure that it’s set up correctly for your monitor and GPU. You may want to back this file up before making any changes. Lastly, to gather more insights about the current driver state, executingnvidia-smiin the terminal can provide real-time information that may help diagnose the underlying problem. Remember to approach any changes cautiously to avoid further complicating the setup you’ve invested so much time in.
