Does UI not responding fixed yet? I got this problem from the 1.0 and 1.1. When this happened Bluetooth mouse can automatically connect and I can move mouse pointer around but UI can not interactions at all.

Ok, I think I have the same problem. But using joycons as mouse it works.

So just to be sure, you did delete the boot folder and boot.scr file, right?
I'm not sure if it was originally under the 1.2 edit, but it caught my eye this morning and I'm about to check if it worked now.

What sd cards are you using by the way? The Samsung EVO 64gb doesn't seem to work, at least for me.

Yes, I deleted the boot folder and boot.scr.

I use this SD cards:

I think there's an issue with fast cards, so it probably will be a wait for 1.3. None of mine are working so far.

Anyone managed to get past the Launcher for Minecraft: Java yet?

I use that same Intenso class 10 card in a 16gb variant and it works for me. Albeit it being very slow performance wise.
Download sd card formatter and format your card first.
then download Balenaetcher and flash the card that way. THEN simply copy and paste the patch into the already existing root directory of the fat32 partition.

@bylaws and @CTCaer Is it possible to implement that when it enters the Dock it enters 2.Ghz and in handhield 1Ghz or 500 Mhz?

Strangely i can't seem to resize my parition in linux ater upgrading to 1.2, i've just done a fresh install and that's usually part of my initial setup. I've got errors when doing it the last 3 times and then L4T fails to boot after doing it each time.

Is this a known bug? searched for it in the thread but couldn't find anything. After resizing it says I have no space left also.

Still getting this even after switching SD card.

Error is "Error resizing filesystem on /dev/mmcblk0p2: Process recorded exit code 1:resize2fs 1.44.1
resize2fs: Permission denied to resize filesystem (udsisks-error-quark, 0)

EDIT: Problem does not persist in 1.1 - could possible be one of the changes made to help with SD card issues is messing with the partitions resizing?

 

[Drban789]

just a few question.

What is the risk of running ubuntu. I heard about previous versions had a high risk of screen burn.

If i run ubuntu do i need to keep the switch always in sleep mode after use and use a payload to boot up ubuntu if it turns off.

Finally, is running ubuntu forcing the switch to overclock at all times or when running things specifically. I just wanted to use ubuntu to watch youtube and anime and stuff maybe play some web browser games. How bad is the battery drain?

Is there any way to play andriod games via emulator on ubuntu?

If anyone can answer these questions i would appreciate it.

Why are XFCE4/LXDE the only DE where the touch screen functions won't rotate with the screen?

Also LXDE is the goat.

• The real time clock gets messed up in horizon

Excuse me, but is it dangerous, for Horizon OS?
Is it irreversible?
What's the RTC is all about?
Can you please explain it a bit in a dumb language? (:

the clock temporarily gets messed up, it’s not dangerous, just connect the system to the internet in Horizon

Could you please post a link to the Samsung SD card formatter software?
I can't find it on Google..

They probably misunderstood it as a CPU "clock" which is understandable, for a second I actually thought it would mess up Horizons CPU clock speed

Unfortunately, PCSX2 is built around x86, and won't work on ARM64

Maybe they will move it to X64 someday. They should. X86 is getting old those days!
