General Support / Re: Major freezing issues with Uburmix 3.0 on Acer Travelmate B115 (WORKAROUND tho)

« Last post by urkomasse on August 28, 2016, 10:55:07 PM »

I may have found a really really really good solution:
https://bugzilla.kernel.org/show_bug.cgi?id=109051#c436


Two scripts are provided by the author of that post, a couple of posts above (and again right below).
One of them disables all C6 power-saving states, and enables the C7 states. Apparently Bay Trail Intel CPUs have a bug with C6 states.
Using this script from /etc/rc.local, you should be able to run Bay Trail devices with standard kernels, without any parameters, and still with battery saving.
I will test later, but it sounds really good!

I am testing today with the latest standard kernel of Ubuntu 16.04, 4.4.0-34, and it seems very stable. I think the Ubuntu kernel developers may have backported the fixes.

This is great news for a lot of people out there


EDIT: Looks like I spoke too soon. According to the kernel bug report, people are still experiencing the freezes with kernel 4.4.0-34.
I am going to test kernel 4.6.7 (I am having a separate issue with ath10k_pci wifi and kernel 4.7.2, so I am hunting for a better kernel).
According to the bug report kernel 4.6.3 or higher has solved the issue as well.

Hi,


I am running my Asus TP200SA (or E205SA) laptops with standard Ubuntu for this reason. By applying the latest kernel 4.7.2 from the Ubuntu Mainline Kernel PPA, I have managed to get very stable machines, without the cstate parameter.


That parameter turns off powersaving features of the processor, which can increase heat and shortens battery life.
So... I guess it would be great if Jim could make a kernel for Ubermix based on 4.7.2

General Support / Any way to store UEFI settings on an image?

« Last post by tlscott99 on August 07, 2016, 01:51:33 PM »

I have 100+ HP Touchscmart AIO systems to install Ubermix 3.1.  These systems are set to UEFI by default in BIOS.  I can image each system fine if I use the UM 3.1 USB directly on each machine, using UEFI settings.  It boots fine under UEFI.

My question -  is there a way to store the UEFI settings when I create a USB image from this particular computer.  I like to pre-image my hard drives but the UEFI settings don't seem to store the UEFI settings on the UM 3.1 USB I created.

I know I can do each system one at a time, but it would sure help to pre-image the hard drives with a UEFI settings.  Any suggestions?

General Support / Major freezing issues with Uburmix 3.0 on Acer Travelmate B115 (WORKAROUND tho)

I recently installed Ubermix 3.0 on my Acer B115 and it quickly started suffering from complete freezes where nothing (including mouse cursor) would do anything, forcing a restart of the computer using the power button. The freezes would occur between 5 minutes and an hour of booting up the machine - generally closer to 5 minutes.

After some research and failed attempts to fix the problem by installing a new kernel, I came across the workaround that works. Turns out the problem has affected many people and is well documented, but there is a workaround - not a fix, as it causes the machine to be much less power efficient.

The issue is that many Intel Bay Trail machines with kernels newer than Linxu 3.16 have been suffering these system freezes. I see Urku flagged this in comments under the Ubermix 3.0 arrival blog with this link:
https://www.phoronix.com/scan.php?page=news_item&px=Intel-Linux-Bay-Trail-Fail

The workaround is to alter the grub.cfg by adding "intel_idle.max_cstate=1". I found the most useful guide to doing this (although pressing "SHIFT" to acces the POST didn't work - I needed to use "ESCAPE") was this:
http://andylinuxblog.blogspot.co.at/2016/05/asus-aspire-ubuntu-freezing-issue.html

With the workaround, it appears my machine is now working happily, but thought I better share to save others the big headaches I've been suffering trying to fix the issue.

How-to / How do I default the boot to a specific user?

« Last post by JoeMarquez70 on May 27, 2016, 11:15:43 AM »

Hi, I want to know how to boot the Ubermix 2.41 OS to a specific user. The main "User" is set as admin, I want the OS to boot to a "Student User" account I created so they are not given Admin access. Any ideas?

How-to / Wifi Connection Ubermix 2.41 on lenovo X120e

« Last post by JoeMarquez70 on May 27, 2016, 09:25:33 AM »

Hello, I have been using Ubermix 2.21 on old lenovos and they work like a champ. But 2.21 would not load on our little X120e computers, so I tried 2.41 and with a little work they boot up with Ubermix just fine. Question is, how do I log into wifi. On 2.21 I would click on our school connection, change to protected EAP, then type in our username and password and it would log in. Now I still get a list of connections, it takes me to a connection screen, but no way to type in my username/password. There is a "Play" button, but when I press it I get a blinking circle and no progress/no connection. How can I edit the connection to put in the username and password to login?
