a thoughtful use of digital
I had some small problems with stricky notes widgets (windows always in a wrong position). Probably this code helped:
dpkg -l | awk '/^rc/{print $2}' | xargs -r sudo dpkg -P
Purging obsolete configurations (of previously only removed packages).
A good website is Convertio: it can convert, for free, your pdf to an svg absolutely identical, from a graphical point of view, with your original pdf, and the text remain text.
But on the other hand the resulting svg file is much bigger than the original pdf, because it is not optimized at all.
To replace a paragraph <p> of less than x characters (30 in the example below) with a title (<h3> in the same example), you can use this regex code
search: <p>(.{0,29})</p>
replace: <h3>\1</h3>If the re-image pop-up doesn’t disappear after working (ad explained here), try this
`sudo apt install qtchooser`If you get this error message:
You are not authorized to execute this filemaybe your .desktop servicemenus files are not executable.
Ensure that they are.
If you have some layout problems with Cardbook (addressbook manager) in the latest releases of Thunderbird you can try to install the latest release of Cardbook as a file from their website.
Chroot is a very useful feature in Linux systems: you can update a Linux installation on your PC not within that installation, as usually we can do, but from another installation.
I.g. if you have Linux1 on /dev/sda2 and Linux2 on /dev/sda3 and you cannot login into Linux2, you can try to solve the problem by doing an update of Linux2 from Linux1. Using chroot.
There are very good guides on the web, but, let us repeat the essential steps
sudo mount -t ext4 /dev/sda3 /mnt/chroot (note that etx4 is if that is the filesystem, but it could be btrfs as well or another filesystem)sudo mount -t vfat /dev/sda1 /mnt/chroot/boot/efi/for i in dev proc sys run; do sudo mount --bind /$i /mnt/chroot/$i; donesudo chroot /mnt/chrootWhat you do now, within the terminal where you did the chroot is what you could do if you were in that installation (Linux2).
Typically you should do these commands
apt update (without sudo before apt: you are already acting as superuser)Afterwards you can exit with:
for i in /dev /proc /sys /run /; do sudo umount -l /mnt/chroot/$i; done sudo umount /dev/sda2 /mnt/chroot/boot/efi/ sudo umount /dev/sda3 /mnt(chroot Note that these last two commands could be not necessary.
There could be synchronization problems between Thunderbird and the webmail of MS Outlook.
A good, complete guide is here. Because a fault in syncro can be due to the lack of “subscription”, the most important thing is to subscribe all you folders you need to see in TB:
Like in this screenshot:
After months, today I managed to get Kodi work in my OpenATV 7.4. In this way
Now I have Kodi working in OpenaTV 7.4
Warning: with this release (7.4) it occurs that Kodi freezes.
In that case, reboot and put the usb with saved settings.
To solve this problem that could happen with some kernels, you could try to modifiy the file grub in /etc/default.
So that you don’t have more a line like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" (or similar) but a line with only
GRUB_CMDLINE_LINUX_DEFAULT="quiet".
