I’m having trouble increasing my screen resolution on Ubuntu. Despite trying various settings, I can’t seem to get a higher resolution. Can anyone provide guidance on how to resolve this issue?

So, I’ve been wrestling with this screen resolution issue on my Ubuntu setup for the past couple of days, and it’s really starting to drive me up the wall! I’ve got this nice monitor that should support higher resolutions, but for some reason, I can’t seem to make it work. The highest option I get in the display settings is like 1024×768, which feels so outdated. I’ve tried messing around with the settings, but no luck so far.

I read somewhere that Ubuntu can sometimes be a bit finicky with certain monitors or graphics cards, and I think that might be my case. I’ve got an NVIDIA card, which I heard can be a little tricky with Ubuntu. I even installed the proprietary driver from the Additional Drivers tool, but nothing seems to have changed. It’s like my system is just ignoring my monitor’s capabilities. I tried rebooting a few times, thinking maybe a fresh start would help, but nope, still stuck at the same low resolution.

I did some searching online and found some commands to run in the terminal, like `xrandr`. When I run it, I can see that it detects the right monitor and everything, but the available resolutions don’t include anything higher than what I already have. I thought about creating a new resolution using `cvt`, but I’m not entirely sure how that works or if it’s safe to do. Does anyone here have a step-by-step guide that could walk me through how to either get my current display settings to recognize the higher resolution or add a new resolution altogether?

I would really appreciate any tips or tricks you might have. It’s just really frustrating because I know the hardware can do more, but I can’t seem to coax it out of Ubuntu. So, if you’ve faced a similar issue or if you’re a wizard with display settings, your suggestions would be super helpful! Thanks in advance!

    1. If you’re facing resolution issues with your NVIDIA card on Ubuntu, you’re not alone. First, ensure that the proprietary drivers are correctly installed and that you’re using the correct GPU by running the command `nvidia-settings`. This will provide a graphical interface to check your current settings, including the available resolution options. If your monitor is detected but doesn’t list the desired resolutions, it’s possible you might need to manually add them using `xrandr`. To do this, you can generate a modeline for your desired resolution using the `cvt` command. For example, if you want to set a resolution of 1920×1080 at 60 Hz, you’d run `cvt 1920 1080 60`, which will output a modeline that you can then use with `xrandr`.

      After obtaining the modeline, you can add it to your display configuration. Use the command `xrandr –newmode “1920x1080_60.00” [modeline]` where `[modeline]` is the output you got from the `cvt` command. Then, associate this new mode with your display using `xrandr –addmode [display] “1920x1080_60.00″`; replace `[display]` with the name of your display found in the output of `xrandr`. Finally, apply the new resolution with `xrandr –output [display] –mode “1920x1080_60.00″`. If these steps resolve your issue, you can make this change persistent across reboots by adding the commands to your xorg configurations or a startup script. This method is safe and can provide a workaround until the driver issues are resolved.

      Screen Resolution Troubleshooting on Ubuntu

      Sounds like you’re having a rough time with that screen resolution! No worries, you’re not alone in this! Here’s a simple step-by-step guide you can try to fix it. Hopefully, it’ll be a game changer!

      Step 1: Check Current Resolutions

      Start by opening a terminal (you can press Ctrl + Alt + T to do that). Then, type:

      xrandr

      This will show you a list of connected displays and supported resolutions. You mentioned that it only shows up to 1024×768 – let’s see what’s going on. If you see your monitor there, great!

      Step 2: Create a New Resolution

      If you can’t find your desired resolution, you can try creating a new one using cvt. For example, if you want a resolution of 1920×1080, run:

      cvt 1920 1080

      This will give you a modeline, which looks something like this:

      1920x1080 60.00 Hz (with additional data).

      Next, copy everything after the modeline. You’ll need that in the next step!

      Step 3: Add New Mode

      Now you need to add this mode to your display. Run:

      xrandr --newmode "1920x1080_60.00" [your modeline here]

      Replace [your modeline here] with the text you copied from the cvt output.

      Step 4: Attach the Mode to Your Display

      Now, identify your display name from the xrandr output (it might be something like HDMI-1 or VGA-1). Then, attach the new resolution:

      xrandr --addmode HDMI-1 "1920x1080_60.00" (replace HDMI-1 with your display name).

      Step 5: Switch to New Resolution

      Finally, switch to the new resolution with:

      xrandr --output HDMI-1 --mode "1920x1080_60.00"

      Step 6: Make It Permanent

      If this works and you want to keep the settings after a reboot, you can add these commands to your startup applications.

      I hope this helps you get the resolution you want! If anything goes wrong, just ask for help or search online, there’s lots of info out there! Good luck!
