You'll need to do a CD install on a Mac that old.

« on: April 03, 2017, 05:07:11 PM »

General Support / Re: Ubermix wipes out all mounted media on boot!
« on: April 03, 2017, 04:13:56 PM »
Interesting. This shouldn't happen since rc.local should finish before automount, which means the disk shouldn't be there yet. In any event, version 3.22 fixes this, or you can just run
in generic mode and the ubermix-settings package update will fix it. Alternatively, you can replace the
with
Code: [Select]
sudo apt update && sudo apt dist-upgrade in generic mode and the ubermix-settings package update will fix it. Alternatively, you can replace the
Code: [Select]
rm -rf /media/* with
Code: [Select]
for dir in `find /media -maxdepth 2`; do
[ -z "`find $dir -type f`" ] && rm -rf $dir
done

You can clear everything on exit by going to Chrome Settings->Show Advanced Settings->Content Settings and choosing "Keep local data only until I quit my browser".

You shouldn't need to download that individually any more. You should be able to find and install via synaptic or Ubuntu Software center. Or you can install from the terminal with
Code: [Select]
sudo apt-get install gapps-icons-all

You can also try newer firmware, which you can download from http://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/tree/ . For the B115, the firmware is iwlwifi-7260-[version].ucode. ubermix 2.23 already has versions through 12 in it, so you will only want to download newer. Click on the newer file in the list, which will bring up a binary editor, then click the "plain" link at the top to download. Once downloaded, copy into the /lib/firmware folder to install, and reboot.
Note that you will want to download all of the newer versions, since you won't know for sure if the backport driver will use the latest one. The 4.1 driver I built per instructions above only went as high as the "13" version, even though there was a 14 available.

Panama-Buena Vista is also on Aruba and has experienced weird issues, although I think they were able to get them worked out. The 7260 seems to prefer 5GHz, so definitely make sure you are connecting to a capable 5GHz SSID.
You can also try a newer driver from an upstream kernel through the backports project. To do this, first go to the backport page here: https://backports.wiki.kernel.org/index.php/Main_Page then click on the link under "Download" for the current release. Once on that page, download the latest one at the top (I used
backports-4.1.1-1 for this test run) and extract the downloaded file to your Home (user) folder, then follow these steps:
After this is done, test to see if things are better.

- make defconfig-iwlwifi
- make

- reboot

That's not an error. It is installing normally as it should. The home partition is where the user files are, and is handled later in the installation process.

« on: July 03, 2015, 12:37:39 PM »
Sounds like Virtualization is disabled in the BIOS of your machine. Am guessing it's HP, so what you would do is reboot and press the ESC key repeatedly as it turns on until the BIOS menu appears. Look for a BIOS settings option, then for a virtualization option.
If not HP, consult your manufacturer documentation for instructions on getting into the BIOS setup.

Hardware Specific / Re: Travelmate B115 Touchpad
« on: July 03, 2015, 12:35:06 PM »
The "jumping all over the screen" issue is usually a bad touchpad or a bad connection inside the machine. First thing to try is the connection, which can be easily reseated by removing the bottom panel. If that doesn't work, replacing the touchpad typically does the trick.
FYI, if you want to upgrade the BIOS to 1.26, we built a usb key that will automatically do it for you. You have to switch the BIOS to Legacy mode for it to work, however, then reset everything to UEFI per the instructions on the wiki page. Download the image here https://drive.google.com/file/d/0B52M_cKAX2ARZXpfSTM5dTE5R0k/view?usp=sharing and create the key just like you do for a standard ubermix key (see Download and Install instructions) replacing "ubermix-key2.xx.img with "bios126.img"

2.23 should be better with that device. The Intel driver installer from the prior instructions actually only updated the Intel kernel driver to Linux 3.16 version. As of ubermix 2.2, the 3.16 kernel is the default.
All that said, I have built a backport package for the Intel kernel driver from the 3.19 kernel that you can download from here: https://drive.google.com/file/d/0B52M_cKAX2ARREJiZWl0c0FoUjA/view?usp=sharing . On the B115s, I'm seeing better performance and improved battery life with the newer driver. Should work on all Intel laptops, and I plan to include it as a default in a future build, once I've been able to test it a little more.
You might also try updating the user-space (ie xorg server) drivers, which include a lot of the 3D code, to see if you can eek out a little more performance. There is some risk in that these are typically nightly builds of upstream updates, so you'll want to be sure to test them fully before you deploy at scale. To install, do the following from the terminal (ctrl-alt-t) - preferably in generic mode:
I haven't seen a huge difference in performance myself - your mileage may vary.

How-to / Re: Can I install Ubermix on Windows tablet
« on: July 03, 2015, 12:05:51 PM »
Not on the W3. It has a special Atom processor that is hardware locked to Windows 8. Ubermix does work on higher-end, non-Atom tablets, like the Switch 11.
