Radeon Mobility M6 LY on Debian Squeeze

Upgrading from Debian Lenny to Squeeze, those having this old embedded video card (my laptop is an IBM Thinkpad R40) have found their video performance dropped. This is due to debian’s policy which produced the distribution of this video card’s firmware in a package that is not installed by default with the x.org driver. In lspci -nn, the card is shown as

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon Mobility M6 LY [1002:4c59]

After some browsing I’ve found out that this card is part of the R100 family, so the firmware you are searching for are contained in:

sudo apt-get install firmware-linux-nonfree

Make sure that /etc/X11/xorg.conf, if any, uses driver radeon or ati (which redirects to radeon). So in your xorg.conf there must be something like:

Section "Device"
        Identifier      "ATI"
        Driver          "ati"
EndSection

When you are done, you must restart Gnome (or whatever starts X):

sudo service gdm restart

Limiting access to some users in vsftpd

If you want a subset of your users to have access to your vsftpd FTP server, edit /etc/vsftpd.conf adding the following:

# Activate only users in /etc/vsftpd.enabledusers
userlist_deny=NO
userlist_enable=YES
userlist_file=/etc/vsftpd.enabledusers

The file /etc/vsftpd.enabledusers must contain the list of users enabled to access the FTP service, one per line. Be sure to also add the support for local users:

local_enable=YES

You may also want to fix the home directory, for example to /var/www/:

local_root=/var/www
