The latest version of this OS came out last year. I installed it like a breeze on a Compaq Evo with an HP1740 LCD, and it worked perfectly (using 5.7GB), even through my KVM switch, which other distros sometimes choke on.
What really impressed me?
Slack boots to a console for login by default, so you can upgrade without stuffing up the X-server.
It still uses lilo for boot management, which is so much easier to configure than grub2.
Xfce ran without a hitch using startx.
Even better, ctrl+alt+bksp killed the X-server, so no more configuring this key combination with ’setxkbmap -option terminate:ctrl_alt_bksp’ as you have to in other ‘modern’ distros.
And amazingly, with no X-server running, just on the bare login console, movies play perfectly using the frame buffer, because Slack had created the device /dev/fb0 by default on booting:
$ mplayer movie.avi
MPlayer 20101218-4.5.1 (C) 2000-2010 MPlayer Team
Playing movie.avi.
vo: couldn’t open the X11 display ()!
VO: [fbdev] 640×480 => 640×480 BGRA
The only small quibble I have is that 13.37 perpetuates the brain-dead /bin/df of recent times, which can’t get the root filesystem device right, even though the OS has access to that info:
$ /bin/df -HPT
Filesystem Type Size Used Avail Use% Mounted on
/dev/root ext4 12G 5.7G 5.3G 52% /
Easily fixed, however, with this kludge:
$ /bin/df -HPT|sed s/root/$(/bin/ls -l /dev/root|awk ‘{print $NF}’)/
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda1 ext4 12G 5.7G 5.3G 52% /
What a distro!
I have been seeing this broken /bin/df problem for over two months now, and I thought that was long enough for it to be fixed — but no, someone somewhere must think it is already producing the correct output. It is not.
The problem is in the advanced Linux distros, where /bin/df reports that the root filesystem is mounted on root, which is pretty pointless — after all, that is the definition of the root filesystem. Worse than that, /bin/df now fails to report which device the root filesystem is on, and cannot even report the file type, even though all that information is available to the operating system.
Research on the ‘web seems to suggest two reasons for this recent weird behaviour: implementation of ’systemd’ and a careless soft link of /etc/mtab to /proc/self/mounts. I have developed a workaround which restores the normal default behaviour, with the correct root device and type displayed, and it shall be placed on our website in a couple of days in the “Tutorials” section.
The Linux Supporters Group Adelaide will meet on the above date at the Adelaide South West Community Centre, 171 Sturt Street, Adelaide, commencing at 7.30pm.
We shall have a “Micro Talk-Fest” where all attendees talk for up to ten minutes on a computing subject they are currently dealing with.
Subjects so far are: Impressive (app.); FreeBSD & Linux; Number System development; Rosegarden composing (app.); Image processing; and the Halting problem.
We will supply refreshments, wine and nibbles. No extra cost, still only $3.00. All Welcome.
