| Synopsis: This page is aimed at newcomers not used to the command line. It is easy to change a driver in graphic mode with the Mageia Control Center, except when the driver in question is the graphic one and that nothing can be seen any more ! This page explains how to change it in pure command line, thanks to a console (tty). |
Contents
Method
If the graphic driver isn't correct, Mageia boot freezes and this kind of screen below doesn't progress any more, or sometimes the screen stay totally black, maybe with a blinking cursor.

Open a console (tty) typing simultaneously the keys Alt+Ctrl+F3
As login, enter root, then the password (it isn't displayed)
[root@localhost~]#
Once connected as root -there is the # symbol- enter the command drakconf, the command line equivalent to the Mageia Control Center, and then press Enter. (You can equally use the short form "mcc" for drakconf, remember "Mageia Control Center".)
| # drakconf |
Here, use the key TAB to go from the list to OK, to Cancel, then to the list again. Inside the list, chose the item Display with the arrows keys up and down. Display is highlighted, type TAB to select OK and press Enter

| Keep the changes?
The current configuration is: |
| Disable Ctrl-Alt-Backspace: No |
| 3D hardware acceleration: No |
| Keyboard layout: |
| Mouse type: |
| Monitor: |
| Monitor HorizSync: |
| Monitor VertRefresh: |
| Graphic card: Advenced Micro Device, Inc. [AMD/ATI] ATI Radeon HD 6400 and
later (radeon) |
| Résolution: Automatic |
| Xorg driver: ati |
| < Yes > < No > |
Just press Enter.
| drakx11 |
| You need to reboot for chanfes to take effect |
| < OK > |
When back at the prompt, enter the command reboot to make the system shutdown and reboot.
| # reboot |
From now, the PC will start with the new driver and it will be possible to continue the neat configuration in graphic mode with the Mageia Control Center or whatever you are used to.
If it still do not work, try another driver. I.e for nvidia most works usably with nouveau or modesetting. Just to get it to desktop to work more easily, maybe try vesa, it have low resolution and performance but works with many GPU.
A help is available here: Setup the graphical server
Other obstacles
If using LUKS encrypted partitions: When booting in text mode, the question asking for password get scrolled away. Just start typing the password when scrolling have stopped.
Kernel version
It have happened that booting an elder kernel may work better. Example when a dkms operation failed for some reason, such as out of disk space or other interruption, or vendor not supporting the newer kernel.
-> Select an elder kernel in the boot menu, the line containing "Advanced".
Changing Display Manager
The program that present the graphical user login and desktop selection.
| # drakdm |
Make sure your system is updated
See Errata: Remedies.
Make sure your desktop system is complete
Make sure you have a task-* package for your favourite desktop installed. This ensures no needed packages for the desktop will be missing after the upgrade. Example: task-plasma5. If you don't need full Plasma set it is task-plasma5-minimal. Other desktops follow the same scheme, like task-gnome, task-xfce, etc, some have the "-minimal" variant too.
So as an exampe for minimal Plasma:
| # urpmi task-plasma5-minimal |
More tools
Several of the Mageia Control Centre tools works in "graphical emulating" text mode, most of them available, just launch MCC and select.
| # mcc |
And then there are all command line commands of course...
