Brave et chrome ne s'ouvre plus après installation et démarrage de Zorin 18
Try to switch to Xorg. Logout and at login click on your username then a cog wheal appears at the bottom right corner. There select Zorin Desktop on Xorg.
If it not helps you can try to disable the hardware acceleration in the browsers. If they don't open at all, launch them via terminal with disabled gpu,
e.g.
brave-browser --disable-gpu
google-chrome --disable-gpu
These commands are only for the .deb versions of the browsers, not for flatpaks.
Can you give more information. Include some details of specification of your PC.
Do we assume Brave browser is that which is bundled with ZorinOS 18 Core?
How did you install Chrome?
What was the sequence of events that resulted in browsers not opening?
(edit: I now accept Forpli can type faster than I can
)
