Hello there is my problem but first some info.
Intel Core 2 Quad Q6600
Nvidia 8800 GTS 320mo
3 Go DDR 2
320 Go HDD
Mint was installed correctly, with default partition settings. I just installed some soft from the manager and did not do uninstall of pre-installed soft, I just change de graphcard driver from free to non-free.
This mornig I restarted my computer, it boot properly and come the log on screen with part of texts written normaly and other par very very small, they are so small I can't read them. I login fine but after I just got a black screen with the cursor and the cinnamon menu and in this menu some icon are kind of glitchy. I can move the cursor bot clicking is not working.
I try to log in an other TTY and start X from there but same problem but with a big white square in the middle of the screen.
Actually I don't know what to do so I came here for some help.
If you need more info ask me.
ps : I'm not sure to be in the right sub forum I hesitate with this and "Installation & Boot" if a moderator can help me for that it would be very nice ^^
