Yes to both.

In theory it doesn't sound so bad, in practice it is a worse Switch and even worse at running Linux that a regular Switch.

worse than a PC is clear, but the Lite shouldn't be worse than a normal Mariko switch. can you prove that somehow?

Google the list of games that outright run worse on the Switch Lite or not run at all.

ubuntu on my switch LITE everything works for me, but there is one glitch:
in any program, for example, in a bowser has automatic scrolling down
this happens on two different consoles

I encountered a similar issue with my Switch Lite. I fixed it by increasing the deadzone in /usr/share/X11/xorg.conf.d/50-joystick.conf. Add the following lines to "Switch Controllers" section and adjust the deadzone to your desired value (max value is 30000):
# Left stick Option "MapAxis1" "mode=relative axis=+1x deadzone=9000" Option "MapAxis2" "mode=relative axis=+1y deadzone=9000" # Right stick Option "MapAxis3" "mode=relative axis=+1zx deadzone=10000" Option "MapAxis4" "mode=relative axis=+1zy deadzone=10000"

The reason is that your joycons are drift. You can work around by increasing the deadzone.

How performance is on this linux build? Can you emulate Wind Waker and Twilight Princes with dolphin in full speed? I ask cause i have poor Android performance in those two games.

I just tested the Wind Waker. The speed is around 65% and FPS is 20. It's too slow to be playable.

New link for Ubuntu 5.1.1 :

What did you get installed? Latest kernel, from sources, or base ubuntu image. If latest, it runs so much better. lol. so does Android Pie, which is also still in development. That being said, everything you need is on gitlab, excepting the working sc7 entry, and the rebootstub from atmosphere.
Hekate does exactly that, we use u-boot, grub is for x86, and screen doesnt come up until X starts, so grub probably wont happen. There is reboot2payload that will reboot from linux/android/atmosphere back to hekate, or you could disable reboot2payload, and autorcm, and it will reboot back to stock hos directly, but you will have to inject something everytime you boot, there is no cold boot option.

I know this is way old. But I really need help with the SC7-entry. I've tried two different releases of L4t and it's gets to load but I get L4T Error loading SC7-Entry. Every time. I can't find a fix anywhere. This thread is the only mention of the SC7-entry I could find.
EDIT: I managed to install. I used the 3.2.0 october 2020 for. I guess from here I can just update.

[Quattro74]

So Can I just flash Jammy on top of this install when I'm ready to upgrade? Using latest Hecate? Or can I run the upgrade on Bionic, from the command line?

How’s the performance of this nowadays? I’m trying to find a good way to play pokerogue on my Nintendo switch and the android side of things seem a bit lacking both due to the game not really supporting Android TV and we’ll android TV being hella slow on the switch
