Xorg configuration
The Linutop Configuration Editor allows you to select various screen resolutions, but you can use your own xorg.conf.
Your custom configuration file can be created by hand, or using the debian tools:
sudo dpkg-reconfigure xserver-xorg
Make sure to select the amd driver.
Once your configuration is ready, save /etc/X11/xorg.conf as /cdrom/etc/xorg.conf (i.e. copy the file in the etc/ dir at the root on the first USB key partition).
This configuration file will be used when booting the Linutop, overriding the configuration set with the Linutop Configuration Editor.
For some screens you will need to redefine "modelines" in xorg.conf (see for instance the file /etc/X11/xorg.con.elarge in Linutop OS 2.0.1). The tool gtf creates the modelines using the screensize and the refreshing rate:
gauvain@zero:~$ gtf 1366 768 60 # 1368x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 85.86 MHz Modeline "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync
Do not start X after the boot
If you want to start your linutop in text mode, you can simply add the noX option in the default kernel options (in /cdrom/syslinux.cfg).
The ttys will be activated if you select a text boot (they are disabled otherwise).
The default user login is linutop, and the password is blank.
