Blurry screen during and after install process

Question

Alright so I've been stumped on this issue for a while now and I'm not sure how to fix it. I'm trying to migrate from Windows 8.1 however when I try to install Ubuntu (or any other OS that supports secure boot) the screen is really blurry during and after the install process. I took a picture of what it's looking like

from farther away it looks worse and I can barely make anything out. I'm not sure how to go about solving this issue so any assistance would be greatly appreciated.

Motherboard - ASUS M5A97 R2.0

Graphics Card - NVIDIA GTX 750 Ti

Answer 1

I had the same issue with my GTX 750 Ti. I was able to resolve it with the following steps:

1. Add nomodeset to bootloader (How do I set 'nomodeset' after I've already installed Ubuntu?)

2. Run the following commands in terminal:

   sudo add-apt-repository -y ppa:xorg-edgers/ppa
   sudo apt-get update
   sudo apt-get install nvidia-346
   

3. Restart the computer

4. Remove the repository after restart (Thanks @Pilot6 ):

   sudo add-apt-repository -r ppa:xorg-edgers/ppa
   

Step #1 is just to get you into the terminal since everything on the OS is blurry otherwise.

Answer 2

It looks to me as if your X installation is running at too low of a resolution. Try this for diagnostics (and maybe to fix it):

1. Open System Settings.
2. Select Displays.
3. Look at the value next to Resolution. Ideally, it will match the maximum resolution of your monitor. If it is, then something else is the cause; but if it's ridiculously low, that confirms my hypothesis.
4. If the Resolution value is too low, click it and see if there are other options. If you're very lucky, you'll be able to adjust the resolution to something reasonable.

If the resolution is too low but you can't increase it, there are other ways to adjust it, as described in these questions/answers:

• How do I set the correct monitor resolution with Nvidia drivers for a monitor that does not send EDID?
• Xubuntu 14.04: Screen Resolution 1440x900, no xorg.conf or lightdm.conf
• How do I configure a xorg.conf to use my monitor's native resolution?
• Nvidia drivers seem to ignore customized xorg.conf in 13.10? How to configure?

There are others along the same lines.

Answer 3

I've had the same issue. Installed on multi monitors but disconnecting them after install and reconnecting them so they were redetected fixed the issue.

I now have the issue again on install after messing up my earlier success by trying to update to 15.04.

Back at the installer again. All is blurry. But changed monitors from a Benq which wants to run at 1920x1080 to a 720p TV has given me a readable screen. I know this isn't a perfect answer but it's an answer that works.

Answer 4

Boot from the Ubuntu installation media.
Highlight Try Ubuntu without installing.

Press the E key - add nouveau.modeset=0 at the end of the linux line.
Then press the F10 key to boot the Ubuntu Live desktop environment.

After having installed Ubuntu repeat the same on the first system start.
Highlight the Ubuntu entry in the GRUB boot menu, add the parameter.

Boot Ubuntu and install the proprietary NVIDIA drivers ... reboot the OS.
From now on you don't have to modify the Ubuntu menu entry anymore.

Try installing this using a basic video driver. When I have my server, sometimes I have to run it using a basic video driver.
