Panasonic CF-R7 on Linux

Specs for my CF-R7 Japanese Model.

CPU: Intel Core 2 Duo U7500 @ 1.06GHz
Memory: 1GB 533MHz
Graphics: Mobile GM965/GL960 Integrated Graphics Controller
Chipset: 82801H (ICH8 Family)
Network: 88E8055 PCI-E Gigabit Ethernet Controller vendor: Marvell Technology Group Ltd.
WiFi: PRO/Wireless 4965 AG or AGN Network Connection vendor: Intel Corporation

In Ubuntu nearly everything works out of the box:

WiFi: works out of the box

Ethernet: not tried yet

SDHC: works out of the box (never worked for me on the r3)

Hotkeys: Recognized by Gnome but are not working (need to try to find a fix)

Displaybrightness: Doesn’t work at all. Tried pcc_acpi driver on kernel  2.6.22 and 2.6.24 without any luck. Both are also not working with xbacklight.

Suspend to Ram: works out of the box

Frequency Management: works out of the box

Got a new machine – CF-R7

Last week I got a new notebook. First I was thinking of getting the Panasonic CF-R6 but later I realized that 2GB of memory can be very fine so I decided to get a new one and so I chose the CF-R7 which comes with 1GB memory a 80GB HDD and a Intel core2duo processor. It came in a very small package.

The first thing I realized is, that they added a small fan on the back. I was not that happy at first, but I realized by the time that it is very silent.
Since I am no Vista user I installed Ubuntu Gutsy Gibbon.

Everything worked quite out of the box even the sdhc card reader in the front. The only thing which is not working is the feature to change the display brightness with the hotkeys. I tried everything sofar but no luck at all.

After some days of working with it I can say that I am very happy with this machine. Its small, fast, light, not easy to break and runs quite long on the battery.

Network Manager Causing High Load

Sometimes when I wake up my Ubuntu laptop from suspend mode, it is the case that the Network Manager is having 100% load. I can’t connect to any network, so nothing is working. If you restarted your computer at this point and also get in the checking hdd routine, then your are in bad mood, well at least I was.

A solution I am using is, simply kill the process and restart it again. How to do this?
Just run the two following commands.

sudo killall -9 NetworkManager
sudo /etc/dbus-1/event.d/25NetworkManager start

After a short time the Network Manager starts searching for the Network connection and you are ready to roll.
