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
SATA-Controller: 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller
HDD: TOSHIBA MK8037GS 80GB
PCMCIA: RL5c476 II Ricoh Co Ltd
SDHC: R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter Ricoh Co Ltd
Battery: Lithium Ion Battery 41760mWh @7.2V

In Ubuntu nearly everything works out of the box:

Graphics: needs some tricks to work with compiz -> driver is blacklisted

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

    Cheers,

    That would be great if you can post your results. I am still struggeling with the backlight. Also pdated to Hardy dev kernel but still no luck. Another guy got it working on a panasonic with a newer kernel, but he was not using the CF-R7, some other toughbook afair

    Hi Schoash,

    OK, after a weekend of anxiety, I’m sad to say that I’m dual-booting.

    Linux Mint 4.0 (Gutsy with packages and slick look) had trouble installing, but after a re-burned iso (at s.l.o.w setting on the burner), initial partition setup through a feisty iso, it installed and ran fine as long as I used F6 to do silent install. Everything worked out of the box, except the following:

    Touchpad – small screen and small pad and fast movement of cursor is a bad combination for me. I tried to slow down cursor movement through Gsynaptics et cetera, but couldn’t. In Vista I just drag the slider and its slow.

    Brightness is on-off, the function keys all work fine with volume (don’t use OSS mixer, ALSA works), but not on brightness. Desktop effects don’t work either, it must be due to the graphics chipset being blacklisted. I did the install of the synaptics drivers for the chipset, no effect.

    In the end, I accepted that one of the main reasons for getting the thing was battery life, and with all the Panasonic utilities in Vista it works quite well. In Linux, with full brightness, I was having 2-3 hours battery and a hot computer.

    Interesting with Hardy alpha – I think that if our chipset gets supported, the brightness would be fixed, and we I could leave evil M$.

    Oh, and Conics are STUNNING! I managed to wipe out my backup of Vista with all the drivers and utilities in the linux debacle, and Brett at Conics went so far as to put all the material on an ftp server for my instant download. Would Maplin or Wal-mart do that?

    And ANOTHER thing – a question actually – when I press on the bulge over the screen, the lid, the bulge flexes a lot. I doubt whether it would hold against 100 kg. I’m 70 kg, and I think if I stood on it, the screen would surely break. Does your R7 flex like that?

    Cheers,

    Niklas

    Congrats to your new laptop!

    With the touchpad scrolling from left to right i can go until 2/3 of the screen. Dunno if that is fast.
    Still interesting for me that the brightness it at least on and off. In my case it is doing really nothing. At the moment I am changing brightness with suspend and while waking up i adjust the brightness.
    I disabled the Desktop effects, I had the driver whitelisted, but it used too much ressources. Hope hardy will support it. Well I am still thinking if I should upgrade to Hardy. I am using the OS in a production environment, dunno if that is very intelligent.
    I ordered my laptop here in Japan. I got a CD with it I suppose there is a Vista on it. In Europe we don’t have any of the shops you mentioned.
    Concerning the display back. I read that the 100kg are also meant that the small clip at the display hood will stand 100kg. But somehow I can imageine putting 100kg on it, of course when the lid is closed because the keyboard and the whole construction should hold. I can’t really say that mine flexes a lot. Just a bit like the R3 did. The thing I am missing is the wateroulet on the bottom. I checked the W and Y series, they all have a hole in the bottom where the water which you can put on the keyboard will flow through. I couldn’t find this on the R.

    Is there any news for ubuntu on the R7? I bought one and am waiting for it to arrive. Did you try to resolve the display problems via https://lists.ubuntu.com/archives/ubuntu-users/2005-October/054477.html?

    I’d be pleased to hear from you!

    I am running the R7 always with the latest updates. For the screen brightness, I came across the xandr thing. You can change the brightness on the terminal with xbacklight=x where x ={0-100}. To enable this u need to run xrandr –output LVDS –set BACKLIGHT_CONTROL native. Changing it with the keyboard doesn’t work in this version of Ubuntu out of the box.

    Has anyone tried Ibex on the R7 – any luck?

    Cheers,

    I’m in a love/hate relationship with digital memory because of how prices are always,and I domean always dropping. I absolutely hate buying SD Cards for my R4 / R4i at (what seems to be) a bargain price only to see it become 10% cheaper a couple of weeks later.(Posted from rrPost for R4i Nintendo DS.)
