Canaima GNU/Linux es una distribución con configuraciones y controladores a veces diferentes a las de otras distros. Cambiar la resolución de pantalla puede desencadenar problemas visibles como texto que se muestra en rojo (o con colores incorrectos), tamaños de fuente desproporcionados o interfaces que se “rompen”. Es importante distinguir entre dos escenarios distintos:
Este artículo cubre ambos: causas, cómo diagnosticar, y soluciones prácticas para usuarios y administradores.
Si los dos métodos anteriores fallan y las letras rojas siguen apareciendo, el problema está en el servidor X.

If the screen is stuck on a black screen with red letters upon startup, or the boot text is too large/small, you need to modify the GRUB configuration.
Step 1: Open the Terminal
If you are in the "red letters" screen, try pressing Ctrl + Alt + F1 to access a text terminal (TTY), or if you are on the desktop, open the terminal (black screen icon).
Step 2: Edit GRUB Configuration Type the following command to edit the bootloader configuration file: cambiar resolucion de pantalla canaima letras rojas
sudo nano /etc/default/grub
(You will need the root password, which is usually canaima or root depending on the generation).
Step 3: Modify the Resolution Line
Look for the line that says:
#GRUB_GFXMODE=640x480
It should look like this:
GRUB_GFXMODE=1024x600
Step 4: Update GRUB
Save the file by pressing Ctrl + O (Write Out) and Enter, then Ctrl + X to exit.
Now, apply the changes by typing: Canaima GNU/Linux es una distribución con configuraciones y
sudo update-grub
Step 5: Reboot
sudo reboot
This should fix the boot resolution, ensuring the "red letters" menu and the subsequent loading screen fit the screen properly.
