Pressing any button (e.g. letter) types it twice in 1.8.0 lazarus / 9-Editor ---------------------------------------------------------------------- vlastimil · 2017-12-07 05:10 Hello, OS: Linux Mint 18.3 Cinnamon 64-bit. I am a recreational user of Lazarus and an advanced user of Linux. I have just edited my Q&A of how to install Lazarus on Linux Mint 18 and installed it: https://unix.stackexchange.com/questions/299758/lazarus-ide-not- correctly-installable-from-repository-in-mint-18-x Now, what is the problem: When I type, IT TYPES EVERYTHING TWICE, literally. See image in attachment. I want to start a new project, hence I need this resolved soon. Thank you. EDIT1: I have found that if I launch lazarus with sudo, it types normal. Where could be the problem? ---------------------------------------------------------------------- Handoko · 2017-12-07 06:15 Hello vlastimil, Welcome to the forum. This issue happens on Ubuntu, its variants and/or GNOME Desktop users. It has been reported here: https://bugs.freepascal.org/view.php?id=30863 You can find the solutions here: http://wiki.freepascal.org/Lazarus_Faq#Typing_in_edit_fields_generate_ duplicate_letters I personally choose to disable the Input Manager. To do it on Ubuntu Mate: Ubuntu main menu > System > Control Center > Language Support > Keyboard input method system > select: none. ---edit--- After you change the setting, you need to restart your computer. ---------------------------------------------------------------------- vlastimil · 2017-12-07 06:22 Alright, there has been some XIM selected in Input Method in System Settings. But the problem persists after setting it to NONE. Any further things I could try? ---------------------------------------------------------------------- vlastimil · 2017-12-07 06:30 Ok, problem resolved with that setting AND reboot. Thank you very much. ---------------------------------------------------------------------- avra · 2017-12-07 07:50 Quote from: Handoko on December 07, 2017, 07:15:08 amThis issue happens on Ubuntu and its variants.It also happens on Manjaro Cinnamon. On Manjaro XFCE it does not happen. I gave up Cinnamon because of this bug.
