I started with Linux on an old craptop that I was planning on throwing away. Useless old a10 7300 with no dGPU. The install went well on that and I’ve never really had any problems, so when I got my new laptop I was psyched about putting it on my new T480, i7 8650u, 32gb ram, 1440p and mx150. The first problem started with the live usb. The first time I tried it, using the same drive from my previous install, it was unbearably laggy, even after a relaunch. I tried to get over it and proceed with the install only for it to crash. The way I’ve done both my new and old installs are though partitioning in windows and filling the partition in the installer, so I wasn’t worried about it corrupting anything. After the first one failed, I reformatted it with the most recent version of Manjaro and the live usb worked fine and installed fine. Now when I try to start Manjaro there is a whole host of problems, most of which I can’t even explain.
Quite literally every time I boot into it something new is awry. At first it was slow to boot and login, and because of the higher-res screen, the text was small. It first crashed while opening settings literally 10 seconds into having it open. The second time it froze on the desktop (Note: both of these “crashes” are weird because there is no error message, and I can still move the cursor but literally everything else is non-functional). After a couple of more attempts, it sorta works but now everything is dreadfully slow; the command prompt takes 15 seconds to open and has a jittery opening animation and the cursor only sometimes moves smoothly. I tried to run some of the diagnostic commands that people have recommended but it quite literally won’t give anything in response and half the time will just freeze like previously mentioned. Most recently I booted into a black screen with the GUI terminal floating in the middle of nowhere and the cursor on the screen.
I don’t have a clue what to do or how to solve this but my best guess is its a dGPU issue. I don’t know how to go about fixing this either, and someone on Reddit was talking about downloading some version with free vs non-free drivers, but I’m not quite sure what that is all about. I know about drivers and Nvidia optimus because I’m generally good with windows but I’m still brand new to Linux so… here I am. Thanks for any responses in advanced.
