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

« 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?

Hardware Specific / Hangs at Loading Ubermix...

« on: February 02, 2016, 08:49:09 PM »

Installed 2.24 on Thinkpad T60.  Once installed, it works fine on the first bootup.  I shutdown, then restart.  It hangs at "Loading Ubermix...".  I've tried reinstalling several times and tried different hard drives - same result.

Any suggestions?

General Support / How to make Ubermix 2.1L automatically start DVDs - solved

« on: September 25, 2014, 09:36:55 PM »

I use Ubermix 2.1L for older computers that are refurbished and given to students.  One of the problems that I encountered was that some students reported the system would not play commercial DVDs.  After verifying it wasn't a DVD drive hardware problem, I determined that Ubuntu 14.04 really doesn't have the final step done to allow DVDs to play.  Here's all that is required to get UM 2.1L starting and playing DVDs without problem.

1. From the desktop, use CTRL-ALT-T to get to the command line.  Make sure you are connected to a network.

2. Type the following on the command line:  sudo /usr/share/doc/libdvdread4/install-css.sh

3. After it finishes, close the terminal window.  Put in a DVD.  When it starts, you are asked to verify the application to use.  I use the default (videos) and check the box to always use this application.

4. DVD will run as expected.

I would guess this should be done then apply simple updates so you won't need to do this on each installation.  Maybe it can already be done in the next UM version?

General Support / 2.1L simple updates not working

« on: September 09, 2014, 03:27:27 PM »

I work with a computer refurbishing group and we've been using 2.1L which works great with older systems, but I've run into a problem I didn't see in previous UM versions.

After putting a few shortcuts on the desktop and modifying LibreOffice to write MS Office files, I attempt to get simple updates working.   As in the past, I used menu choice 5 from the flash drive boot, then create simple updates, they seem to write to the flash drive without a problem. 

However, when I attempt to use them on another system (choosing #4 Fast Image or just choosing #2 Simple updates) there are some problems.  First, the whole process looks normal, but it finishes without any notification, just going back to the UM main menu on the flash drive.  When I attempt to just press enter to reboot, it wants to start the whole imaging process again.  I've let it go through again, but seems to get stuck in a loop.  If I interrupt the process, then reboot the system that has just been imaged, it doesn't want to keep the simple updates.  It also does something weird with the home partition, making it only about 8 GB regardless of the size of the hard drive.

I can continue to use 2.1L by itself with no problems, but just have to make the changes (desktop icons, LibreOffice config) manually on each system imaged.  It would be nice to have simple updates working again.

I have tried this using different flash drives and different computer hardware - same result.  Any suggestions?

General Discussion / UberMix on Mac Mini

« on: February 17, 2014, 09:21:20 PM »

Our organization (2nd Chance Computers - Modesto) recently received several Intel-based Mac Mini's as donations.  Since our goal is distribute computers free to students, preferably using UberMix, we set a goal to install UberMix 1.3 on the Mini. 

As it turned out it wasn't as complicated as we anticipated.  We were able to boot a USB Parted Magic to wipe the drive, but later couldn't get the USB UM image to boot.  Finally I downloaded the CD-based UM iso, which booted directly to the USB UM image.  The UM image installed at normal speed without problems. 

The biggest problem I had was getting the boot CD out of the drive so the hard drive could boot.  After a little researching, it turns out you can hold down the left mouse button on boot to eject the CD.  After that the system booted easily with no errors on first boot.

I hope this helps anyone who has older Intel-based Mac Minis.

General Support / Problem with UM 1.3

« on: September 08, 2013, 11:27:44 AM »

Using 1.3 I have a problem that I didn't encounter in 1.083.   Basically the boot process just loops with a flash of a mouse cursor, followed by a blank screen, repeating the process indefinitely.

I verified the download checksum, installed on 2 different flash drives, installed on 4 different hard drives, installed on 2 different computers with completely different motherboards and video.  I.083 works fine on all of these hard drives, computers, and flash drives.

Not sure what to make of it.  I can email a video of the process if needed, but doesn't look like the forum will allow me to upload much.

Anyone else having problems with 1.3?  Any suggestions will be appreciated.

Hardware Specific / Missing Letters using UM 1.082 on Dell Dimension 2400

« on: August 28, 2013, 10:25:11 PM »

I am using UberMix 1.082 on a variety of both older laptops and desktop that I donate to students.  It has been working great on 99% of all the systems on which it is installed.

However, I've run into a problem that is obviously a video card drive issue.  When the system boots, the text menus are missing many letters.  When I go to a terminal and type "sudo restart lightdm" everything comes back to normal.  I've tried putting "nomodeset" as suggested places in grub (as per other forum posts), but all it does is come up in 640x480 resolution.

The computer is a Dell Dimension 2400 with an Intel Corporation 82845G/GL on board video card (as per lspci).

Any suggestions?
