A typical use case is when an editor is setting its window title to the full long path name such that the actual important part, the file name, falls off the edge on the right and becomes invisible. Unfortunately the X11 window title is normally set internally by the application and its format is hard coded. A solution is to monitor the editor window title and modify it if its becomes too long.Continue reading Change X11 window title

I want to use my new USB drive exclusively with Linux, so I decided to wipe the factory default partitions and create a new ext4 filesystem on the drive. The drive uses 4096 byte physical sectors and we have to make sure that the new partition is correctly aligned. For some background information on partition alignment, see this link.
Check that we are wiping the correct drive
sudo parted /dev/sdb unit s print free
Note the details in case you want to restore the original partitioning scheme. Information on the factory default can also be found here.Continue reading Repartition a new USB drive

It is a great lightweight document viewer which does what I need most of the time. One exception is when after opening a PDF file from Firefox I decide to keep the file and select File Save As. Atril insists on saving the file in $HOME/Documents, which is practically never the directory I want to use…Continue reading Atril (evince, document viewer) default directory for Save As
In XFCE when you move a window around and it gets close to the top edge of the screen it suddenly jumps to maximised size – this is never what I want and so I find this feature really annoying.
The setting where this feature can be turned off is hidden in a somewhat counter intuitive location:
Yes, the setting is called ‘Accessibility – Automatically tile …’!
Occasionally when my scanner is emailing me a PDF it gets corrupted along the way. Most of the time the individual scanned images in the PDF are either perfectly valid or at least can viewed, even though the PDF viewer refuses to open the corrupt PDF file.
The bash script below will extract the images and then combine them again into a valid new PDF file.Continue reading Recovery of scanned PDF corrupted by email transfer
