Sony Vaio SE - Card reader, fn button

Hi all,

I've just got a Vaio SE and put fedora 16 onto it. With the release kernel, I had some pretty serious throttling issues. With the latest kernel from yum (3.2.9-1.fc16.x86_64), it is not so bad, but I still see a little throttling in the CPU. Can anyone let me know how to control this?

Secondly, my fn keys never worked at all. I've no idea where to start looking or why. Any help appreciated.

Thirdly, card reader does not seem to work.

Code:
[root@yaxattax-vse acpi_call]# lspci
00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09)

05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
[root@yaxattax-vse acpi_call]#
Is the card reader the Unassigned class device? Where should I begin looking with this one?

Fourth. I am using LXDE, and the battery indicator applet always says 100% - is there a better way I can show remaining battery somewhere on my user interface?

Fifth - /proc/acpi/battery existed with kernel 3.1.0-7.fc16.x86_64 but with the new kernel it does not. Why is this, and is there an alternative location? I know acpi -i gives some info, but the info from these files was more detailed.

Finally, I appreciate everyones time taken to look at this, and any help will be much appreciated.

Regards,

Yax

Re: Sony Vaio SE - Card reader, fn button

So some updates:

I've found where the new battery acpi file lives, its in the /sys/ file tree.

I've found that my fn keys don't work because I am using lxde. I've found the following guide http://wiki.lxde.org/en/LXDE:Questio...eyboard_events that should help me to sort out backlight keyboard events with a bit of effort.

I found the cpupower command, and have added "cpupower set -b 0" to my rc.local to try to get maximum performance from it. Will see how that pans out.

No progress on the card reader or the battery remaining applet.

Will post with more updates as I get along.

Re: Sony Vaio SE - Card reader, fn button

Found the card reader:

Code:
[root@yaxattax-vse ~]# lsusb

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 004: ID 8086:0189 Intel Corp. 
Bus 001 Device 005: ID 05ca:18c0 Ricoh Co., Ltd 
[root@yaxattax-vse ~]#
Not recognising devices still. I've no idea why.

Fixed my fn keys. Using xev, one finds out what keystroke is the result from keypresses, and then writes it into their LXDE config ($HOME/.config/openbox/lxde-rc.xml) like so:

Code:
  <keyboard>
    <!-- Laptop Key bindings for brightness control-->
    <keybind key="XF86MonBrightnessUp">
      <action name="Execute">
        <command>xbacklight -inc 15</command>
      </action>
    </keybind>
    <keybind key="XF86MonBrightnessDown">
      <action name="Execute">
        <command>xbacklight -dec 10</command>
      </action>
    </keybind>
Code:
yum install xbacklight
Change the keybind key="" based on what you find the keystroke for your laptops button combination is. I understand laptops may ue non-standard keystrokes. Alternatively, map brightness up and down to any arbitrary key if one is that way inclined.

Code:
cat /sys/class/power_supply/BATN/uevent
Nice summmary of what all the individual other files contain in the same locations.

Still no progress on lxde battery monitor applet. Might be rolling my own.

Re: Sony Vaio SE - Card reader, fn button

I found out that the "Unassigned class" from lspci was indeed my card reader. Managed tp find device drivers for it - have to compile the kernel module myself. The drivers are licenced under GPL so I'm not sure why they are not distributed with the kernel. Never mind

Re: Sony Vaio SE - Card reader, fn button

Fellow SE 15 inch user here.

The main issue I had was battery, and the laptop getting very hot. This was solved by installing the latest fglrx from ATI, they seem to have finally produced a driver that at least tries to make hybrid cards work. After installing, I turned down the gpu acceleration to the minimum and I get what appears to be the same temperature / fan action as in Windows. I have not managed to make the switch to the intel gpu work through the ATI control centre, however.

Since SE users may read this, just a note advising you that the current fglrx driver doesn't work with F17/rawhide and they'll be stuck with fans blasting. I wasn't able to get any results through vgaswitcharoo on F17, I got intel gpu up and the ati off, but fans were blasting. I'd wait for the next fglrx before upgrading. Apologies for going slightly offtopic here.

Also, the Fn buttons and their respective shortcuts work fine on Gnome3 out of the box, for what it's worth.

Hi Fortean,

Maybe offtopic, but appreciated - I'll at least know what to do if I should want to activate my radeon graphics now

Cheers,

Yax

Re: Sony Vaio SE - Card reader, fn button

I would put Fedora in a VM. No driver issues.
