Problems with Alienware Graphics Amplifie

in flag

I am using Alienware 15r3 + Alienware Graphics Amplifier with RTX 2060 Super connected to external monitor. I have run into multiple problems. Ubuntu 21.10 installs with nouveau drivers as default. Before changing the drivers to official ones I have to change gdm to lightDM (if not my system becomes unbootable). I can’t install the 510 driver (from Softare and Updates) because it makes my system (again) unbootable. I can succesfuly install 470 nvidia drivers but my external display stays blank. I can see that GPU is detected in lspci but when I run nvidia-smi it says that no devices are detected. Does anyone know whar can cause the problem and how to solve it? I am frustrated because I have been fighting with it for 5 days and need my PC functioning ASAP. Thanks in advance

It's best to install the correct drivers during system installation. You must select/accept proprietary software and download updates while installing. After the fact, you can run `sudo ubuntu-drivers autoinstall` to install the recommended driver. However if you've already made several unsuccessful attempts using other methods, you may have done something that prevents you from getting this right.

My all attempts ended with reinstalling Ubuntu. Now I have to reinstall the system again. I’m not sure if the solution you suggested would work. From my knowledge Ubuntu comes with GDM as default Display Manager. As I mentioned I have to replace GDM with LightDM for my system to boot with internal display working.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
