hiya,
i just got my asus 2 days ago and wanted to share my findings with you how to get nearly everthing working:
its an asus a53s which is nearly the same as a k53sv: core i5, 4gb, 500gb wd scorpio blue, gt 540m 2gb vram, cardreader, NO bluetooth
just for the record: it originally came with BIOS version 208, i updated it to 210 and then to version 300 (i thought it would fix fan issues, but it didn't)
still not working:
* camera is upside-down (you can find solutions using google easily or here on the forums / NOT every asus laptop has this problem!) * stability issue #2 (heavy lags resulting in freeze) * harddisk clicking with WD scorpio blue -> try post #33 and report back please :) -this works for me!
what will work after doing these steps:
- stable WLAN (ath9k driver in 2.6.38 natty is buggy)
- Touchpad (2 Finger Scrolling/disable on typing) (will actually get detected as touchpad, not as mouse on default natty install)
- Nvidia offloading through bumblebee WITHOUT the fan going mad (uploaded scripts to bumblebee to fix fan issues)
- fn keys like volume up/down - play/pause/next/prev (see post #9)
- stability issue #1 (related to intel sandybridge drivers - update to patched kernel to fix GUI hangs, try post #25 - works for me | fixed in 2.6.38-11)
- cardreader fix (follow _byrons_ post)
- BLUETOOTH (follow _byrons_ post again :))
not confirmed by anyone expect me
- hdd performance issues (repartition whole drive cause its a 4k advanced format hdd, aligning partition table will fix those small lags - if you don't have 'em, nevermind ;) #5)
WLAN: my hardware:
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)symptoms: slow wlan connection, copying files over LAN normally will work for 5-10 minutes then it will drop completely.. you had to disconnect and connect again to get it working for another 5-10 minutes
one of many bugreports to this problem: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/761176
speed before: 120-170kb/s max.
as 2.6.39 seems to bring new bugs, lets just update (dirty way) the ath9k driver (based on this guide http://ubuntuforums.org/showthread.php?t=1481983)
wget http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.39/compat-wireless-2.6.39-1.tar.bz2
tar xfvj compat-wireless-2.6.39-1.tar.bz2
cd compat-wireless-2.6.39-1
./scripts/driver-select ath9k
make
sudo make install
sudo make unload
sudo modprobe ath9k
or just reboot insteat of the last 2 steps
after driver update: 2500-3000kb/s on g-wlan... same situation :)
Touchpad:
gets detected as mouse so no scrolling etc..
to get it detected and working (can be configured in the "mouse" preferences):
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/681904/comments/64
after following these steps reboot or unload old module and load new one:
sudo rmmod psmouse && sudo modprobe psmouseNvidia offloading/disabling NVIDIA card to get over 4hrs of battery life:
you will need git:
sudo aptitude install gitafter its finished do these steps:
git clone http://github.com/MrMEEE/bumblebee.git
cd bumblebee/
sudo ./install.sh
if you get asked which config you want to use, choose the one from "Thomas Krutz" - this will fix any fan issues
be aware, this will add another xorg ppa to install a newer nvidia driver. but it should work
reboot
you can now try if it worked:
optirun glxgearsand
glxgearsany change to the GL libraries (like bumblebee PPA or xorg-edgers PPA will break intel DRI after installing/setting up bumblebee, so be aware! i think the bumblebee install.sh moves around some files)
hope this helps someone :)
[COLOR="Red"]obsolete as of 4.7.2011
i submitted my enable/disable scripts when you get asked which config you want to use, just choose the one from "Thomas Krutz" [/COLOR]
to disable the nvidia card you can use the following commands:
bumblebee-enablecard, bumblebee-disablecard, ...if you get caught by the same bug as me that after installing bumbleebee and the fan starts spinning at full speed i did this to fix it
in /usr/src/acpi_call-1.0 i modified asus1215n.sh:
#!/bin/sh
# Power control for Asus 1215N Optimus
# by Pete Eberlein
if ! lsmod | grep -q acpi_call; then
echo "Error: acpi_call module not loaded"
exit
fi
acpi_call () {
echo "$*" > /proc/acpi/call
cat /proc/acpi/call
}
case "$1" in
off)
echo _DSM $(acpi_call "\_SB.PCI0.PEGR.GFX0._DSM" \
"{0xF8,0xD8,0x86,0xA4,0xDA,0x0B,0x1B,0x47," \
"0xA7,0x2B,0x60,0x42,0xA6,0xB5,0xBE,0xE0}" \
"0x100 0x1A {0x1,0x0,0x0,0x3}")
# ok to turn off: Buffer {0x59 0x0 0x0 0x11}
# is already off: Buffer {0x41 0x0 0x0 0x11}
echo _PS3 $(acpi_call "\_SB.PCI0.PEGR.GFX0._PS3")
;;
on)
echo _PS0 $(acpi_call "\_SB.PCI0.PEGR.GFX0._PS0")
;;
*)
echo "Usage: $0 [on|off]"
esac
#echo P3MO $(acpi_call "\_SB.PCI0.PEGR.GFX0.P3MO")
echo DGPS $(acpi_call "\_SB.PCI0.PEGR.GFX0.DGPS")
PSC=$(acpi_call "\_SB.PCI0.PEGR.GFX0._PSC")
echo _PSC ${PSC}
case "$PSC" in
0x0)
PSC="on"
;;
0x3)
PSC="off"
;;
esac
echo "Asus 1215N Optimus appears to be ${PSC}"
now you have to edit bumblebee-enablecard and bumblebee-disablecard to use this file: in enablecard: find the last lines
#echo _PS0 $(acpi_call "\_SB.PCI0.PEG1.GFX0.DON")
#echo _PS0 $(acpi_call "\_SB.PCI0.PEGR.GFX0.DON")
modprobe nvidia-currentwrite this right after the commented echo lines in the enablecard script: ``` /full/path/to/asus1215n-modified.sh on
in the disablecard script do the same, put a # on the last line and add/full/path/to/asus1215n-modified.sh off
et voila, turn the pc off to get rid of the full speed fan (reboot wont help) and then boot your ubuntu again.. everything should work now .. at least it does work for me.
