I know that this topic has been touched but not with the same emphasis: I have an 8GB SSD Linux AA1 and A6GB SD card extension. However, the extension is definitely not recognised in the same way as the 8GB SSD. The SSD is now full with some 100MB free. However, that is not enough eg to install open office. This installation obviously needs some space on the SSD. When I came to less than 100MB free, I checked that by deinstalling the SD card, the system becomes unstable and crashes. It tells me before that I am low of memory and should clean up the trash. But the trash is empty. Or I should install an SD extension. However, that does not help since the open office installation AND OTHER APPLICATIONS requires space on the SSD. So I need to free it from unnecessary files and programmes. It appears to me that the system needs for stable operations some 400-600MB free space on the SSD . Is there any idea which files or directories I can delete or move to the 16GB SD card so that I can free space on the SSD? This problem first appeared when I tried to remove openoffice 2.3 and install openoffice 3.1. When the SSD was almost full even with the SD card installed my control panel was destroyed when I rebooted after installing openoffice 3.1 By the way I am using exclusively xfce and not the Limpus/acer desktop. Can I purge the acer desktop installation and save by that space? I am still a Linux newcomer.
