Ubuntu 12.04 - first impressions

Hello,

First of all, I would like to say that I am very happy about the release of the new image.

Installing qt4 works flawlessly now (sudo apt-get install qt4-dev-tools). It was a bit
of a hassle with 11.10, because two packages where missing.

Two remarks:
1. In the boot message you can see:
EXT3-fs: barriers not enabled
This is not good and can cause problems if you turn off the power without giving a shutdown
command first. See: https://bugs.launchpad.net/ubuntu/+sour ... ug/1097042
I added the line:
/dev/root / ext3 rw,relatime,errors=continue,barrier=1,data=writeback 0 0
to the file /etc/fstab and hope that this fixed the issue, but it would be better to change the
default in the kernel image.

2. I see the following lines in the output of the dmesg:
[ 6.919318] Activating ethernet physical layer Micrel KSZ9031 Gigabit PHY.
[ 9.356990] ERROR: v4l2 capture: slave not found!
[ 9.364598] ERROR: v4l2 capture: slave not found!

It looks for me as if the kernel is trying to find the camera for a few seconds and than gives up.
(I have no camera). Is it possible to disable the camera driver to speed up the boot
process?

Best regards and keep up the good work:

- The DNS /etc/resolv.conf still configured to seco network on the udoo_quad_ubuntu1204_v2.0.img !

- Still have random name (number) to my periph eth and wlan
need to edit sudo nano /etc/udev/rules.d/70-persistent-net.rules to fix that

- I hope dvb-usb modules will be enabled by default soon

 

Module fuse still not there ... but ntfs-3g is installed, this doesnt even make sense for me ...

 

another thing here, i run glxgears or glmark2 and there is no image, black screen (window)

 

Can't say I've tried glmark2, but does the 12.04 image have GL drivers?


I need hard float and GLES2 for openFrameworks, so I suppose I will be waiting a while.

 

OpenGL problems have gone once I've installed Unity.
That means:

Code:

sudo apt-get install unity

Reboot UDOO then logout from desktop, a login screen will be shown, click in the Ubuntu logo near the label "Ubuntu" (just above the password text box) and select "Ubuntu 2D", now your graphics session will use Unity and OpenGL apps run correctly!

 

Thanks. This was helpful. I followed instructions, but seem to get Gnome running inside of Unity. Strange. -Noel

 

Solved the issue for me too thanks. However everything runs much slower now.

 

Alas, it will run slower.

However Team UDOO are working on a Distro that will run like greased lightning so lets hope Santa brings us that!

 

Super!

 

I edited my /etc/NetworkManager/NetworkManager.conf file to comment out the dns=dnsmasq line out, but I still get the seco.it search domain and the 192.168.0.X or 192.168.2.X name servers configured after doing a dpkg reconfigure resolvconf.

It does pick my name servers that are fed to it via dhcp, but anyone have suggestions around how do I remove the original entries from being populated?

Thanks.

 

I think we need to compile the Kernel with needed modules. I don't understand why FUSE was not included. Without using USB discs laying around with mountains of SW and data and not being able to use them...

Where is the kernel source located? Oh and is there a LOADED upgrade perhaps?
