2022-04-28 Thread Daniel van Vugt
I completely agree, it's a bad user experience. The reason why proprietary drivers like Nvidia are historically not installed by default I think is because they have their own license conditions. In practice the real problem here seems to be the bugginess of the open source nouveau driver you

Hi all! I've installed Ubuntu 22.04 for real and using the proprietary driver in fact solves the screen issue. However, in my opinion, someone who wants to try Ubuntu from a live stick should not need to worry about such things (e. g. also try using safe graphics mode). That person is likely to

When you first boot the live USB you should probably choose "Ubuntu (safe graphics)" instead of "Try or Install Ubuntu". Despite sounding different they are the same thing with the only difference being that troublesome graphics drivers are disabled in safe graphics mode. -- You received this

I created a live USB stick with persistent store on it to test the workaround, and the system booted up fine. I didn't get screen where you choose between 'Try Ubuntu' or 'Install', so probably that's why it is working. I checked it and the nouveau driver was selected so i'm not sure if it's

@Daniel - I understand how to troubleshoot things and your steps seems very valid, but I don't have any discrete AMD card right here to test. Also - AMD Ryzen CPUs are not equipped with builtin GPU :) Whole case is about the installation process is simply impossible to be accomplished for

Keep it simple. Please start with only the AMD GPU. If you have a laptop, just disconnect the external monitor. If you have a desktop, just move the monitor connection to the motherboard. You might have to also temporarily remove the Nvidia card during that time or else the system will still

@Daniel - I wish I could but how I can do that, when the screen is totally unreadable (click blindly around especially on 4K display? ;) ) and this is just live USB drive before any installation happening? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs,

Has anyone tried logging into a Wayland session to see if that avoids the bug? On the login screen it will either be called 'Ubuntu on Wayland' or just 'Ubuntu' if the only other option is 'Ubuntu on Xorg'. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs,

I don't want to spend too much time on nouveau bugs when it has so many known problems. So all Nvidia owners please open the 'Additional Drivers' app and install the proprietary Nvidia driver from there. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which

Same here - Nvidia 3060 Ti on AMD X570 platform Panasonic 4K TV via HDMI cable. While welcome screen is fine - the one with "Install" or "try ubuntu", then the screen blink for a while then return with fluo-green-yellow colorset. It is hard to read anything. Re-inserting HDMI cable to force

@Daniel I'll gladly do that, but I won't get my hands on that computer before Thursday and I'd need to either figure out how to create a persistent live stick or to install 22.04 on a separate partition or drive. -- You received this bug notification because you are a member of Ubuntu Desktop
