Exactly. Firefox is faster, smoother use less cpu than Chromium

Is it possible to install the Raspberry Pi Foundation's enhancements to LXDE from Raspbian on this Ubuntu/Linaro build?

It's a voltage issue.

I had a bad power supply, which I replaced, and it eliminated the issue.

After loading Raspian I loaded Mahjongg and Blender neither of which would start. I burned wintrmutes last image and wonder of wonders both started. My only problem now is I can't get a flash drive to mount. I tried "sudo mount /dev/sda /mnt" and got an error. It just plugged in and worked with Raspian, but I think this version will be the way to go once a few little things get mastered. I will try booting with the drive plugged in and see if it mounts on startup.

Anyway I am really optimistic. Blender is a good video editor (as well as many other things and it came up with no hesitation at all).

I plan on hooking up a hard drive that has an USB interface to use for scratch. This little gem of a computer is really neat!

Thanks for the fine work wintrmute :D

A little more info. I plugged in the USB and restarted the system and the volume showed up when I clicked on the file system tool, but when I right clicked on the volume name I got a message saying I wasn't authorized to perform that operation.

I tried editing the /etc/fstab file and adding /dev/sda then doing a sudo mount -a. At first I listed the file system type as vfat and it said it couldn't find a valid vfat filesystem (It is a 64GB stick formatted as fat32) so I gave it a filesystem type of fat32 and it said that wasn't a known filesystem type. As it shows the media label I think it is reading it and it works fine under Raspian so I think it is just ignorance on my part. It has been a long time since I worked with a UNIX system except as a casual user.

Guys this is excellent work.

I'm having some trouble with the latest version though. Raspi-Config doesn't seem to save any changes I make. The overscan setting is now wrong and I have black borders on screen.

I can get in to raspi-config from a terminal window and can make changes but they don't have any effect after a reboot.

Looking forward to giving chromium a good testing in the latest release.

A little time with google and I found "fdisk -l" which showed that I needed to do the mount on /dev/sda1 and I gave it /media as the directory and there it was. Now to get it to mount automagically and give the user permission to use it.

Just edit the config.txt file in the boot partition, overscan option, it works.

BTW, I used Ubuntu Linaro small developer image raspuntu-tjc-2015-02-10.zip, used gparted to resize/extend/ the rootfs partition and installed full version of KDE using: apt-get install kde-full
It installed full Linaro desktop.

I am interested to know how well KDE runs on this as it's quite a bit heavier than Lxde.

You may try out - it takes more than one hour to install the full KDE though.

BTW I found out that the best option to switch between different RPI2 OS is the Berryboot - Boot menu / OS installer for ARM devices:
http://sourceforge.net/projects/berryboot/
They have updated Berryboot Boot menu for RPI2 now and all the links to OS images are working.
The downloading of the OS images with fast DSL connection is going at full speed.
It is possible to try out many different OS images using only one microSD card.

Raspi-config appears to replace my config.txt with a 0byte file.. I would personally use it with extreme caution.. I haven't done any testing In great deal to see exactly what caused it

Is this even permitted?

Code: Select all

wget http://archive.raspberrypi.org/debian/pool/main/p/pistore/pistore_1.1.16693_armhf.deb
sudo dpkg -i pistore_1.1.16693_armhf.deb
sudo apt-get -f install
pistore
It works. I've just been playing Cookie Clicker on Ubuntu Linaro, from the Pi Store...

I've been real pleased with this image, I can read the USB as a user, but still can't write it. I tried: "mount /media -w" after a "umount /media" and have an fstab entry that looks like:"/dev/sda1 /media vfat defaults,rw,user 0 1" although I have no idea what the "defaults" "0" and "1" are for, I was just copying the pattern of the other entries.

Also, is there a video player that uses the hardware? That would just about make it perfect for a desktop. I tried to do a "sudo apt-get install omxplayer --fix-missing" and it couldn't find omxplayer.

I installed LibreOffice yesterday to go with GIMP, Blender and Mahjongg (a personal time waster).

Today I will try plugging in a USB hard drive and doing some video editing, if I can get the permissions set up for writing. I am interested to see if it is possible, if a bit slow. GIMP seems to be useable. Mahjongg is quite acceptable as is LibreOffice.

You could try a debian version from http://omxplayer.sconde.net/.

Install gdebi-core first and then try to install it with gdebi to get the dependencies.
