i'm going INSANE trying to get SANE to work for my Canon Pixma MX300
Try use sane cvs. It support MX300.
Ok , I guide you how to do it eventhough you probably know how (for user who don't know la):
Only applicable to Debian and Ubuntu based.

1. install dependencies for compilation:
CODE
apt-get install libusb-dev


2. Get sane cvs:
CODE
cvs -d :pserver:anonymous@cvs.alioth.debian.org:/cvsroot/sane login
cvs -d :pserver:anonymous@cvs.alioth.debian.org:/cvsroot/sane checkout sane-backends


3. Configure and compile:
CODE
cd sane-backends
/configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make
make install (as root or sudo)


4. Make sure your user is in scanner and plugdev groups.
You can check using command: groups (run this as user)
ex:
CODE
groups
oshiri dialout fax voice cdrom floppy tape sudo audio dip video plugdev games users usb scanner camera vboxusers

If you don't know how to add user to that group, read this: http://mambang.org.my/modules/news/article.php?storyid=134

5. Backup your udev libsane.rules and replace with new one (Use sudo if you using Ubuntu, and root if you using DEBIAN):
i) Backup
CODE
cp /etc/udev/rules.d/025_libsane.rules ~/

(025_libsane.rules is in Debian ETCH. Yours probably different , please check. You can set different path to backup that file)
ii) Overwrite file with new one:
CODE
cp sane-backends/tools/udev/libsane.rules /etc/udev/rules.d/25-libsane.rules

(please change name according to what is given in rule.d directory)

6. Test new sane
i) you could reboot, restart udev service or unplug an replug your scanner
ii) test scanner with all below commands:
CODE
scanimage -V   - to check version of sane. You should get CVS.

scanimage -L    - to list your scanner device or devices

scanimage -T  - to really test your scanner. If you get erorr of I/O, try switch usb port.


That's all.

1. Boot using livecd.
2. Mount read write your first hdd.
3. Chroot to your hdd linux partition
4. Reinstall grub: grub-install /dev/xxx (xxx is your first hdd device)

No, you don't need to reinstall. The partition is still there, the problem is you can't access the boot loader. Man, I think I edi did this before but forgot doh.gif .
Here2, I think I referred to this page last time >> https://help.ubuntu.com/community/Recoverin...stallingWindows

Got problem burning DVDs. Found many complain about this on other forums too... but none seems to have solution.

DVD burning in ubuntu very very slow, and not successful at all. How to do this? I got no problem burning CDs though.

I'm using K3b and Liteon DVDRW

minicom for ncurses based
cutecom for gui

You can apt-get install both.

Check hdparm. Probably dma is off.

ex:
CODE
# hdparm /dev/dvd

/dev/dvd:
IO_support   =  1 (32-bit)
unmaskirq    =  1 (on)
using_dma    =  1 (on)
keepsettings =  0 (off)
readonly     =  0 (off)
readahead    = 256 (on)
HDIO_GETGEO failed: Inappropriate ioctl for device


hdparm is important tools to troubleshoot problem with slow I/O in hdd or cd/dvdrom, especially when you get jerky movie playing.
Some distro disable 32 bit IO and dma in their kernel, probably for compatibility sake. This will slow down reading and writting on hdd or cd/dvd.
You can use hdparm to enable it in userland.

restore grub:

1. masuk cd ubuntut, boot live cd
2. bukak terminal, pastikan lokasi hard disk (/dev/sda1 ke, /dev/sda3 ke...)
3. taip 'grub'
4. taip 'root (hd0,6)' <-- bergantung kepada nombor boot partition
5. taip 'setup (hd0)'
6. taip 'quit'
7. restart dan berdoa
