Q After wiping out the hard drive on my new laptop, I changed back to UEFI and reinstalled Win 10 (wiped the whole disk again) and, after all updates, reinstalled Ubuntu 17.10 as well. Since then I can't get the touchpad to work, everything else does, but the touchpad doesn't even show up in xinput since the change to UEFI.
A (Thanks to original poster msbt in the Ubuntu Forums) I was playing around for days and just now (because it wouldn't shut down properly) I edited grub with acpi=force
sudo nano /etc/default/grub
and put in
GRUB_CMDLINE_LINUX_DEFAULT=“acpi=force”
After reboot the touchpad was working!
Q I was able to access the content of my Android phone by just plugging it into my computer, then something changed and it didn't appear in the file manager.
A You probably implemented a Screen Lock password. Remove the password and you should see the files on the phone.
Q I am in the process of building a computer. The standoffs (included with the case) would not thread into the case. I will be returning the case. Is there any danger in testing the components outside of the case while I am waiting for a new case?
A (Thanks to Autodave in the Ubuntu Forums) The biggest danger is static electricity.
The other dangers are dropping something on the motherboard or spilling some liquid on it.
Q I have an old machine that is running 12.04. The essentials are backed up. Would it make most sense to just install over the top with 18.04?
A (Thanks to strixtux and kc1di in the Ubuntu Forums.) Gord says: switch to Xubuntu or Ubuntu Mate for this older computer.
Try a Live USB or Live DVD to check that the computer can run a current OS. If 18.04 doesn't work, try 16.04.
Swap in a new hard drive and install onto that; you still have the old installation to work with if there's a problem. Put the old drive in an external case so you can easily copy the data files. Once you are happy with the new setup, you can use the old hard drive for backup.
Q How do I change the margins of a Calc spreadsheet?
A (Thanks to KH in ask.libreoffice.org) Click on Format, Page, Margins.
Q I want to print a chart in Calc with the grid lines showing.
A (Thanks to Lupp in ask.libreoffice.org) Choose the option under > 'Format' > 'Page…' > tab 'Sheet'.
Q I'm using Libreoffice 4 on Ubuntu. I'd like to export an existing .docx file to mediawiki language.
A (Thanks to David in ask.libreoffice.org) First: sudo apt install libreoffice-wiki-publisher
After a reboot, you should be able to: File > Export… select MediaWiki | txt in the File type list. Click the Save button.
