Ubuntu and the asus zenbook (UX31)

**Frederik Seidelin** · October 27th, 2011

Hey all,

I know that this probably doesn't apply to this model as it's a different motherboard, BIOS, video card, and what-not. However, it'd be silly to remain silent for that reason if some of this could actually help you in narrowing down the causes of the problems.

I own an ASUS U33Jc laptop (the one made of bamboo), and it has problems with suspend, multitouch, and the processor steaming ahead at 2.53 GHz instead of reducing the clockspeed to the more frugal (and quite sufficient) 1.2 GHz.

Although I can't remember which parts from where, I've used bits and pieces from the links below in making my PC work adequately:

Unfortunately, it would seem that ASUS isn't that Linux-friendly. Previous to this one, I had an Eee 1000, which didn't work OTB either. :-\

Good luck! :-)

For the UX31, I found the page about unbinding the USB drivers before suspending.

^- so the Fix Suspend here worked directly for you?

EDIT:

With this modification (according to the address I found in lsusb -v):

Code:

+EHCI_BUSES="0000:00:1d.0"
-EHCI_BUSES="0000:00:1a.0 0000:00:1d.0"
+XHCI_BUSES="0000:03:00.0"
-XHCI_BUSES="0000:04:00.0"

I get my ssh prompt back after resume instead of a total crash but I'm still not getting my screen back... any idea?

I just figured out the suspend problem with the help of this: http://askubuntu.com/questions/22237...bridge-support

Do this:

1.

Code:

sudo gedit /etc/pm/config.d/unload_module

2. Add

Code:

SUSPEND_MODULES="xhci_hcd"

to that file. Save and exit.
3. Reboot
4. Suspend
5. Resume
6. Profit

Notes:

1. This unloads the USB 3 module before a suspend. I'm pretty sure that it gets reloaded during resume, but that's just a guess. I haven't tested that.

2. If /etc/pm/config.d/unload_module doesn't exist just create it. That's what I did.

3. I don't know if this breaks anything else. I just did this about 5 minutes ago.

Hopefully this works for everyone and we can check this off of the list of issues.

*****************EDIT*************************
THIS DIDN'T ACTUALLY WORK. I JUMPED THE GUN. MUST'VE PRESSED HIBERNATE INSTEAD OF SUSPEND. DISREGARD. SORRY.

*******************NUTHEREDIT********************
It kind of works. Sometimes it will resume. Sometimes not. If I use "fn+F1" it seems to work more often. I don't know. I'm going to go read some logs.

Hi,

Having an interest in purchasing this for linux use I don't see the suspend issues being a problem - they should be easily fixed.

I am more worried about cpu multiplier/frequency scaling. Can someone please confirm what governors are available.

ie do a

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

Cheers

Does the Zenbook have any other issues apart from the suspend one? I'm having a terrible time with my current laptop's hybrid gfx and I'm dead scared of installing on a new machine in case I get the same problems.

google vbetool vberestore {your gpu name} - most of these issues are down to the video card not posting on resume.

Hey Shakabra,

This didn't seem to give me much joy.. I even manually rmmod'd the module before suspending and couldn't get much beyond the familiar lockup.

I'll start perusing some logs too!
