Ubuntu 9.04 beta on 1024x600 model

[kbundies]

I put the new Ubuntu 9.04 beta onto my 2133. I used the alternate install CD, btw.

Added the

Option "PanelSize" "1024x600"

line in the xorg.conf file.

I can confirm that this is working fine.

Only WiFi is flaky. I have the STA Driver activated in Administration/Hardware Drivers. If I deactivate it, I don’t have any wireless.

How can I activate the proposed "Broadcom B43 wireless driver"?
Synaptics showed me a package b43-fwcutter, which I installed and which seemed to pull and install this driver - but I don‘ see a reference of it in the "Hardware Drivers".

So I activated the "Broadcomm STA wireless driver" again. Now, after a restart, it even worked for a while, but then lost the connection (which was 100%, btw.)

Is there a way to fix this issue (may be with the Terminal?

Any help very welcome, thank you!

I have to add, the Wifi/Bluetooth switch does not seem to be able to get switched off. Just stays blue all the time.

I have installed also the Ubuntu 9.04 Beta but the cpu scaling doesn`t work. Somebody a idea?

[kbundies]

Mss,

this is the next thing I got to work by adding something to the GRUB configuration file "menu.lst":

This is a quote form J.A.Watson:

To get CPU frequency scaling to work [...], you have to edit the GRUB configuration file (/boot/grub/menu.lst). Find the line with the kernel boot parameters (generally the first line in the file with “kernel”…), and add

acpi_osi="!Windows 2006"

to that line. After reboot, you can check if CPU scaling is working by adding the Gnome CPU Frequency Scaling Monitor widget to the Panel.

That is only for the general purpose, ACPI controlled CPU freq/power control - - not for the VIA specific enhanced power saver.

[kbundies]

mikez, thank you for your answer.
I, not knowing, what ACPI actually means, was quite happy to see, that I could configure my processor to run on half speed (0.8 instead of 1.6).
"Conservative, Ondemand, Performance, Powersave" or "1.60 GHz, 1.20 GHz, 1 GHz, 800 MHz" options, looked as if they would probably prolong the battery time??
What would be the VIA specific enhanced capabilities?
Thank you for a little hint.

It is called e_powersaver - has about 16 speed/power/voltage steps - the VIA processor can change mode within only a few clock cycles.
One of its few claims to fame (the other being hardware crypto engine built-in).
Stick around - e_powersaver is my next to test feature in Ubuntu-9.04

(The Cloudbook is also a VIA C7M-ULV machine.)

OK - I just checked that out - Ubuntu-9.04 (as of this afternoon's update anyway) - loads the proper VIA cpu controls:

Note: the advice given above about the kernel command line option was from 8.04 **not** 9.04

Translation: If your 9.04 is up to date (you need to update at least daily) - -
Don't mess with the stock setup - it is correct (if your machine shows what my post shows).

[kbundies]

mikez,
so the VIA processor is actually quite an advanced little thing!
You were right,

the advice given above about the kernel command line option was from 8.04 **not** 9.04

but it still seems to work.
Would you suggest, to take that addition from the GRUB menu.lst file?
Do your tests show, that the cpu scaling is working in 9.04 "out of the box" now since todays upgrades?
With best wishes

I have updated my installation, but the cpu frequenz scaling works only with de acpi bootline parameter. :?:
