Install Ubuntu Server 13.04 on PandaBoard
What is needed:
- PandaBoard / PandaBoard ES
- PC/Laptop with sdcard reader
- Latest Ubuntu ARM OMAP4 Image (currently 13.04)
- Windows users: Win32DiskImager (writing the image to sdcard)
What is to do:
- Download latest Ubuntu OMAP Image.
- Insert sdcard in card reader.
- Utilize ‘dmesg’ for checking which adress the scdard was give, schould look similar to this:
[42941.351598] sd 6:0:0:0: Attached scsi generic sg2 type 0 [42941.950455] sd 6:0:0:0: [sdb] 7744512 512-byte logical blocks: (3.96 GB/3.69 GiB) [42941.951532] sd 6:0:0:0: [sdb] Write Protect is off [42941.951543] sd 6:0:0:0: [sdb] Mode Sense: 03 00 00 00 [42941.952596] sd 6:0:0:0: [sdb] No Caching mode page present [42941.952603] sd 6:0:0:0: [sdb] Assuming drive cache: write through [42941.956588] sd 6:0:0:0: [sdb] No Caching mode page present [42941.956596] sd 6:0:0:0: [sdb] Assuming drive cache: write through [42941.966124] sdb: sdb1 sdb2 [42941.969820] sd 6:0:0:0: [sdb] No Caching mode page present [42941.969830] sd 6:0:0:0: [sdb] Assuming drive cache: write through [42941.969837] sd 6:0:0:0: [sdb] Attached SCSI removable disk [42942.732880] EXT4-fs (sdb2): recovery complete [42942.732888] EXT4-fs (sdb2): mounted filesystem with ordered data mode. Opts: (null)
- Write Image to sdcard:
SDCARD=/dev/sdX # X=ermittelte SD-Karte gunzip {path_to_image}.img.gz sudo dd bs=64k of=$SDCARD if={path_to_image}.img sync
Windows users can use Win32DiskImager for steps 2-4:
Choose the unzipped image and drive letter and click write.
Note: I have not tested this, cause I don’t own a windows pc.
Boot/Configuration

Screen tearing when playing flash-videos in unity
In Ubuntu 13.04, as already under 12.10 and 12.04, there is a notable screen tearing problem, when playing videos in fullscreen, using Intel HD 3000 graphics and Unity-Shell.
To resolve this issue, you’ll need CompizConfigSettingsManager:
sudo apt-get install compizconfig-settings-manager
Disable Touchpad while typing
When your curser changes it's position while you are typing, then you propably hit your touchpad accidently…
This should be prevented by a functionality named "disable Touchpad while typing", which should diable your touchpad for a specified interval after pressing a key.
On one of my laptops (a Lenovo IdeaPad Z580 – Synaptics Touchpad) this interval is to short under Ubuntu 12.10 and so is mostly useless.
