Hi, I have Arch Linux ona Dell Laptop (Inspiron 15 7537). The desktop is gnome and it has an elan touchscreen.
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech G100s Optical Gaming Mouse id=11 [slave pointer (2)]
⎜ ↳ ELAN Touchscreen id=13 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=15 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ Sleep Button id=10 [slave keyboard (3)]
↳ Integrated_Webcam_HD id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)]
↳ Dell WMI hotkeys id=16 [slave keyboard (3)]For the most part, the touchscreen works out of the box. I haven't done anything configuration for it. However, qt5 apps and Telegram do not register touch events. The apps I have tried are Telegram, Cutegram, Qupzilla and the lxqt desktop. With chromium, firefox and gnome apps the touch screen works perfectly. This doesn't seem completely limited to qt5 because telegram doesn't work also and it doesn't rely on qt5 at all afaik. Qt4 apps like VLC and Skype work fine.
For example, if I launch qupzilla, I can move the window around using the touchscreen, but if I touch something within the interface like the menu bar, the cursor moves but I can't open a part of the menu such as file or focus on the address bar.
Is this a bug or am I missing a package? I have tried the latest Manjaro Gnome livecd and I do not have these problems.
