Version: svn trunk OS: Linux Context : I have 2 devices connected to my computer ; one is a regular pen tablet , and other one is a Cintiq pen tablet display, but behaves exactly as 2 separated device , a intuos type of tablet + a dvi screen. So, I guess this can be reproduced with 2 regular pen tablet. Problem : While in Gimp and Mypaint, I can switch from one to other one without any problem, In Krita I have the Cintiq one that work ok as expected , and the regular Intuos that map only to a portion of the workspace ( around 1/4 top left of it )but the GUI around the workspace is still correctly mapped. I attached a picture to illustrate the problem ( in green, mapped surface of the regular tablet ) . Reproducible: Didn't try Actual Results: Expected Results:
Created attachment 61340 [details] screen with mapped zone in green of the second tablet running on the system
I also noted the calibration infos I written on my auto-launch script for Wacom like this , was not taken into account by the Krita workspace ( zone to draw ). But for the GUI the calibration is ok. This result by a fringe around the workspace of around visually 15px/20px ( bottom and right ) where my pointer can't access ( it directly jump to the GUI ) xsetwacom --set "Wacom Cintiq 21UX stylus" TopX 327 xsetwacom --set "Wacom Cintiq 21UX stylus" TopY 374 xsetwacom --set "Wacom Cintiq 21UX stylus" BottomX 86436 xsetwacom --set "Wacom Cintiq 21UX stylus" BottomY 65171
I am not sure if I understand what you mean by "but the GUI around the workspace is still correctly mapped", does that means you can access the layer box (or any other dockers) with your intuos A5 ?
Hey Cyrille, Yes, that exact : For the Intuos4 M I can access with a normal behavior the top toolbar , the layer, the toolbox ; all GUI elements around the canvas/workspace. ( all the green zone of the picture in attachement ). The part of the canvas/workspace is streched on the tablet to 1/4 top left of the canvas/workspace For the Cintiq 21UX, the bug is more subtle. The GUI is OK and the workspace don't take into acount the calibration made with Xsetwacom ( I did the calibration using the GUI of xinput_calibrator , a broken calibrator for HAL/X but who return if executed in a terminal the 2 X and Y values I need ). In Gimp and Mypaint ( and other apps as far I tested ) no problem, I can switch from one tablet to the other one.
New behavior, depending the (re)boot ( compiled : Tuesday, June 28 2011 19:00 ) *Intuos 4 A5 is correctly working *Cintiq 21UX doesn't work on all the surface of the workspace/canvas, but only on the 1/4 top-left of it. Only GUI around the workspace/canvas work fine displaying the mouse arrow when I fly over with the stylus. The 1/4 top-left of workspace/canvas is mapped to a surface like 2 time bigger. It mean when pointing the stylus at the center , the outliner of the brush appear on the corner of bottom-right. Workaround solution : Deconnect the USB of the not desired tablet and relaunch Krita. With only 1 tablet connected, the behavior is always good.
Maybe I can actually try to reproduce this locally... I've got an intuos and a graphire, but I never tried to connect both of them at the same time. Chances are we're running into a Qt issue here, though.
the weird thing is that "Xsetwacom" parameters are handled inside the X11 driver (or that is how I understand things). So I am a bit confused at how it affects qt.
I will also try here to connect to my other computer running Krita ( laptop ), and other tablets to see if it's not a local problem . I'm also aware connecting multi-tablet to a system is not something 'regular' , but it can be more and more frequent for tablet-pc or touch-pc + a pen-tablet connected. It's for this case ( for me with a Cintiq ) I try to report.
Now you mention it -- I actually used to have the situation of a tablet laptop with built-in wacom + external tablet, and Cyrille still has that setup, afaik.
Ok, following the solution I found for the neightbours bug about tablet calibration 'https://bugs.kde.org/show_bug.cgi?id=277201' ; I tried to give a try to solve this one. Without success. Here what I tried : With Cintiq ( wacom internal ) and a Bamboo FunA5 connected to my system. 1. First I get the tablet ID name ; with : xinput -list 2. Then I grab and copy all the default existing value from both tablet into Wacominfo temp filename : xsetwacom -s --get "Wacom Cintiq 21UX stylus" all > Wacominfo1 xsetwacom -s --get "Wacom BambooFun 6x8 stylus" all > Wacominfo2 Like this I can extract the default calibration value (BottomX/BottomY/TopX/TopY). 3. Then I edit in admin the Xorg snipet for Wacom tablets : sudo gedit /usr/share/X11/xorg.conf.d/50-wacom.conf and I paste in this related to the data I get on my Wacominfo files : Section "InputClass" Identifier "calibration" MatchProduct "Wacom Cintiq 21UX" Option "TopX" "327" Option "TopY" "374" Option "BottomX" "86436" Option "BottomY" "65171" EndSection Section "InputClass" Identifier "calibration" MatchProduct "Wacom BambooFun 6x8" Option "TopX" "0" Option "TopY" "0" Option "BottomX" "21648" Option "BottomY" "13530" EndSection 4. After reboot and re-run Krita; it seams to not solve the problem. Cintiq is correctly mapped and calibrated ; but the bamboo fun have cursor mapped over the GUI element correctly ; but most of the part of the surface is mapped to a tiny upper left rectangle area of the painting workspace. So, as in the first post ; the bug persist.
Argh...
I'm afraid that this is Qt/Wacom driver/X11 issue -- not something we can do anything about ourselves :-(
Git commit 6fc08ccb4884cb193a9044a71c7a419fed53075a by Dmitry Kazakov. Committed on 02/04/2013 at 15:11. Pushed by dkazakov into branch 'master'. Added a workaround for a bug in Qt in 2 monitors + 2 tablets setup This patch effectively rescales the hiResGlobalPos() when sees it jumps to insane values.
