Bug Description
Using Onboard, when trying to type a letter with accent, as á or à, Xorg crashes. This computer has a touch screen: some of its software is intended to be used with the touch screen and, as the screen can be rotated independently from the keyboard, the physical keyboard is not always available.
As in Portuguese many words have accents, this crash would be extremely common.
Regarding Xorg, I had to add the following settings to enable the touch screen:
Section "InputClass"
Identifier "HID Touchscreen"
MatchUSBID "22b9:0005"
Driver "evdev"
Option "Emulate3Buttons" "false"
Option "ButtonMapping" "1 0 0 0 0 0 0 0 0 0 0 0 0 0"
EndSection
Regarding Onboard, only the theme was changed.
The operating system is Xubuntu 18.04 amd64. lspci -v output is below:

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https:/ /errors. ubuntu. com/user/ ID where ID is the content of file /var/lib/ whoopsie/ whoopsie- id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.
