Tips for running Mandriva 2008 on a Toshiba Satellite M200

KRandRTray
If you have a Intel Graphics card like mine, you can't miss out trying KRandRTray. You'll have access to all the functions of the video card, like clone / extended desktop and even rotate. It's excellent for working with projectors.

Toshiba Fn Hotkeys
As to be expected, not all the hotkeys would work. Luckily all the important ones did. Already working were the LCD/VGA display switcher, brightness up/down and suspend to ram key. The keys that will not work are the media player, lock pc, backlight off, suspend to disk, wifi scan & touchpad toggle keys. To enable the other hotkeys on this Toshiba, you will need to change the keyboard type, the standard installation set the keyboard to a "Generic 105 key (Intl) PC" keyboard. You will need to change this in Mandriva Control Center (MCC), under Hardware->Set up keyboard layout->Keyboard type-> Select Toshiba Satellite S3000. This will enable the remaining hotkeys, namely Wifi killswitch, Volume dial, browser, play/pause, stop, prev & next keys.

LCD Brightness
In Mandriva 2007.1, the LCD is brightness can't be changed by either the hotkeys or kpowersave. I had to resort to a hack using /proc/acpi and laptop-mode. This time round the LCD brightness worked with the hotkeys & kpowersave but reacted strangely to the brightness slider in kpowersave, as you slid down the bar the brightness would go up & down erratically. Eventually I discovered again through /proc/acpi that only the following percentages worked 10 25 35 50 60 75 100. Using these values in the kpowersave profiles worked very well. Any other value would set the brightness to the lowest.

Chicony 1.3MP Webcam
This webcam works very well in aMSN. It's a little iffy in Kopete with intermittent color. Completely useless in Pidgin.

Some compiz-fusion bugs
There only 3 bugs with compiz-fusion that I've encountered. First is an issue with the kscreensaver whereby the screensaver will come out but not cover the whole screen as it should. This can be solved by using the workaround in CompizConfig Settings Manager (ccsm) called 'Fullscreen Legacy Support'. However locking the screen using the lock button still causes the issue. The second bug is an intermittent issue when I login in & out of a session, sometimes the hot corners / screen edges stop working until I open ccsm & make some changes. The final bug is a intermittent crash of compiz-window-decorator whenever I switch the K Menu button to another style, such as Kickoff or Default KDE. The issue only occurs during the change, once done it does work fine.

That's all I can write about this topic, Mandriva has been working great so far on this laptop & is actually giving me very decent (better than Windows Vista) battery life. I'm lovin' it.
