Linux su un ASUS A6R (A6RP)

So it came the day my old Acer died... actually it didn't, but I managed to break the display, and the repair cost was WAAAAAY too much to be repaired, so I decided that it wasn't going to happen.

This left me without a laptop, and shopping for a new one. I discounted most machines (especially new Acer Aspires that didn't looked tough enough for the job) and in the end I picked a new ASUS A6R.

The machine is a Celeron M 1.8 Ghz, with 1 Gb of ram and it was shipped with an 80 Gb disk. I didn't wanted to mess around so I just moved my old 120 Gb disk from the Acer to the ASUS, this saved me a lot of time in installation and personalziation but I had to start with the vanilla kernel. The video card is an ATI Radeon XPress 200M with 128 Mb of shared ram, this left me with a tad less than 900 Mb for normal use.

Since I was at it, I updated from Slack 10.2 to 11. The update was flawless, it simply started up without an hitch.

   

   

The Asus came with a widescreen display, now, I'm not particolarly fond of widescreen display, but since 90% of laptops now are equipped with this stuff, I had to use it. The only thing I had to do to use the display was to configure X to run at 1280x800 pixels. The standard VESA driver worked nicely enough.

Section "Screen"
  Identifier "Screen0"
  Device     "Videocard0"
  Monitor    "Monitor0"
  DefaultDepth     24
  SubSection "Display"
     Viewport   0 0
     Depth     24
     Modes    "1280x800" "1280x1024@60Hz" 
  EndSubSection
EndSection

Note that in the modes I've left a 1280x1024@60Hz mode, this is to use the laptop with an external display (non-widescreen).

To improve the quality of the display I decide to bit the bullet and install the proprietary ATI driver. The driver can be download from the AMD/Ati website: http://ati.amd.com/support/driver.html.

Once installed the display quality improved. I had to tamper a little bit with the X configuration because I didn't liked the way the automatic installer did it. So I changed it like this:

Section "Device"
  Identifier  "Videocard0"
  Driver      "fglrx"
  BoardName   "ATI Radeon Xpress 200M"
EndSection

The dual-head display worked fine with the new version of ATI drivers (available from Jan 2008 from ATI's website, but not really much with the previous version.

Here is the Xorg.conf, it's not very dissimilar from the standard one and the only difference is the ati-configured bit. I've also added the 'Xinerama' option to have the display extend into the external monitor.

It worked fine with the default kernel. Based on lspci it's an ATI card but on my system it works with an Intel hda driver.

The internal wireless is a Broadcom BCM4318 (AirForce), that seems supported by kernel 2.6.17 and newer, unfortunately, for some reason I couldn't use any 2.6 kernel (see section 'things that didn't worked'), so I decided to use Ndiswrapper. Getting the driver from ASUS was simple enough ( http://support.asus.com/download/download.aspx?SLanguage=en-us&model=A6R) get the .inf and .sys files out of the cab file using unshield (it's an Install Shield CAB file) and you're set.

The internal modem (winmodem), but actually I didn't even tried to make it work, I don't use it anyway so...

Suspend-to-disk, never used in my life.
