Unable to Launch LPT

[zachcygan]

I am new to Linux and believe I have bunged something up on the install process. I am currently running on a gnome DE on Pop!_OS.

I believe I installed Flutter correctly, but when I try to open the AppImage the window is completely black and I have to force close it. I did encounter an issue where instead of a black screen it said "unable to create a GL context".

I haven't changed anything and after a reboot once I open the AppImage I can see the packages I want to install, but it either crashes/closes almost immediately or freezes and I have to force quit.

[gaikwadyash905]

can you please share the output?

[zachcygan]

@gaikwadyash905 I am pretty new to linux. What output are you looking for? How do I get it?

[gaikwadyash905]

Try running appimage through the terminal, it'll definitely show the error in the terminal output screen while your gui is running/crashing.

And you mentioned the error: "unable to create a GL context".
Also you can Try this command, it might work:
./YourAppImage --no-sandbox --disable-gpu

I opened it, it froze, I force closed it. I tried installing libcanberra-gtk-module, but it was already installed.

I'm new to linux as a desktop os. I have some experience with headless. canberra-gtk-module is already installed.

I get this when launching as user:
ryandurbin@pop-os:~/Downloads$ ./LinuxPowerToys-0.9-x86_64.AppImage

And this when I run as sudo:
