[Desktop-packages] [Bug 863154] Re: Wacom Bamboo One tablet random coordinate malfunctions
@yorugecko: Viewed the video at http://www.youtube.com/watch?v=MuL2RGTnl1I. Could you be more specific regarding what you mean by "a partial upgrade"? I seem to have the bug over multiple desktop versions of Ubuntu 11.10 with GIMP and two Genius Mousepad 8x6 tablets. For me the symptoms are least using XUBUNTU desktop but still present. It takes me maybe a minute to 90 seconds for it to show up drawing in pencil mode doing fast circles by hand. Could you try scribbling for about three minutes just in pencil mode and see what happens rather than jumping around different functions. If the problem doesn't show up then give us a rundown on what you did to fix it. If you have a fix go over to www.davidrevoy.com and tell David so he can test and post it on his blog. He is the art director for the Blender Foundation and a lot of people in the computer graphics art community are pulling their hair out over this. He has a setup for installing and modifying Linux Mint ver. 11.04 to prevent having various annoying bugs.

GIMP 2.7.4 nightly builds now compile on 64bit Ubuntu 11.10, while previously version 2.7.3 would not (see posts #40 and #44). The following commands will install this unstable work in progress: Open command prompt run the following commands sudo add-apt-repository ppa:matthaeus123/mrw-gimp-svn Update the source list sudo apt-get update Upgrade gimp using the following command sudo apt-get dist-upgrade While this version does not fix the problem with data loss while drawing very fast (line breaks) there appears to be less of a drop-out problem and the line thins right before the line breaks. Then there is a recovery with a thin line and then it goes back to a normal pressure drawing line again. This is somewhat different then what I described in Post #44 and #45 regarding GIMP 2.7.3. There you would be drawing a line and it would just break and then reappear as you did quick scribbling of large circles. I noted that today there was also an update of UPSTART version 1.3-0ubuntu11 which is an "event-based init daemon" a 288kB download, which might be relevant. UPSTART is a replacement for the /sbin/init daemon which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running. It appears the frequency of streaking lines to the edge of the windows in GIMP 2.6 may have also lessened somewhat but is still present. In either case 2.6.11 or 2.7.4 there seems to be somewhat of an improvement over two weeks ago. Has anyone else noticed this? To reproduce this bug set GIMP to draw with Pencil in NORMAL mode, set brush to ROUND FUZZY, point size to 6, set to BASIC DYNAMICS, leave all other settings in 0.00 or their defaults in the left-hand window. Set your tablet to SCREEN configuration. Then try and draw big sweeping circles quickly in a window set for say 800x600 at 96dpi. There is no problem at all... as long as you don't draw real fast in ver. 2.7.4... which is kind of a show-stopper for most. Note that I am using the Genius Mousepad 8x6 tablets because my daughter and I am just getting into this and I didn't want to shoot for WACOMs. So WACOM users should try this and see how it works in your environment and report back here because this is the most substantial thread on this bug problem. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/863154 Title: Wacom Bamboo One tablet random coordinate malfunctions Status in The GNU Image Manipulation Program (GIMP): Unknown Status in “gimp” package in Ubuntu: Confirmed Bug description: The tablet in overall seems to work correctly, with all pressure- features working.

[Desktop-packages] [Bug 863154] Re: Wacom Bamboo One tablet random coordinate malfunctions
My bad! Post #63 describes data loss in GIMP ver. 2.7.4 with thin lines. This is due to using a different Brush than previously. The standard GIMP Brush does not produce thin lines but complete data loss while GIMP Brushes #1 and #2 give the thin lines before and after dropouts. Just loaded the Linux Mint 11 Gnome Live CD and tried drawing in Gimp 2.6.11 without tablet drivers installed for my Genius Mousepad 8x6 and without NVIDIA drivers installed. It worked absolutely perfect! No streaks to the edge of the screen at all. No dropouts in the lines whatsoever. Full pressure sensitivity was observed. Scribbled as fast as I could with no problems. But then again Linux Mint 11 is based on UBUNTU 11.04 and everything works fine there. The Linux Mint 12 release candidate will be available around November 11th, based on UBUNTU 11.10. But they are using Gnome 3.2 with Mint Gnome Shell Extentions (MGSE) and MATE to replace Gnome 2.32 instead of Unity and Gnome Classic. This presents and interesting opportunity to see if Unity has screwed up things in UBUNTU since Linux Mint 12 RC is a permutation of Ubuntu 11.10. I will pursue the Linux Mint 12 RC to test against the bug here in Ubuntu and report back. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/863154 Title: Wacom Bamboo One tablet random coordinate malfunctions Status in The GNU Image Manipulation Program (GIMP): Unknown Status in “gimp” package in Ubuntu: Confirmed Bug description: The tablet in overall seems to work correctly, with all pressure- features working.

LINUX MINT 12 Release Candidate TEST of 64-bit DVD Version downstream development of UBUNTU 11.10 Version. http://ftp.heanet.ie/pub/linuxmint.com/testing/linuxmint-12-gnome-dvd- 64bit-rc.iso Released November 10th, 2011, Time: 9:16 1.0 GB Download Bug persists in GIMP 2.6.11 with streaks to the edge of the screen using Genius Mousepad 8x6 tablet and pen. In Gnome 3.2.1 with MGSE, the bug is horrific. In MATE desktop environment the bug is significantly less. It is even less in Gnome Classic and least apparent in Gnome Classic (No Effects) desktop environments. The same is true of the bug manifestation in UBUNTU 11.10 from worst to least: UNITY > Gnome Classic = Lubuntu = Xubuntu > Gnome Classic No Effects. So trying to evade this bug by jumping to the upcoming version of Linux Mint 12 will not help at this time. In fact, the Gnome 3.2.1 3D environment was so bad that the drawing could not keep up with pen movement in addition to having to deal with the spontaneous streaking from the bug. I am running a triple core AMD CPU at 3.1 GHz so this graphics performance is disastrous. The performance was irrelevant to whether my tablet drivers were installed or removed. This leaves only two options: 1) Drop-kick back to UBUNTU 11.04/Linux Mint 11, or, 2) Try another distribution of Linux along Debian development design. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/863154 Title: Wacom Bamboo One tablet random coordinate malfunctions Status in The GNU Image Manipulation Program (GIMP): Unknown Status in “gimp” package in Ubuntu: Confirmed Bug description: The tablet in overall seems to work correctly, with all pressure- features working.

Experiencing same horizontal and vertical line spikes utilizing two Genius Mousepad 8x6 tablets on both 386 and AMD-64 Ubuntu 11.10 machines utilizing latest NVIDIA 280 drivers and GIMP Editor. Confirm that disabling the Extended Input Devices stops the problem. However, without Extended Input Devices enabled the tablets will not have pressure sensitivity capabilities. This problem did not exist in UBUNTU 11.04. Tested and Confirmed this problem pertaining GIMP with the following UBUNTU 11.10 shells: GNOME, GNOME Classic, UNITY, UNITY 2D, Lubuntu, LXDE Session, Xubuntu, Xfce Session Additionally Martin Owens PPA for Wizardpen Drivers does not include the latest version for Oneiric Ocelot 11.10 https://launchpad.net/~doctormo/+archive/xorg-wizardpen deb http://ppa.launchpad.net/doctormo/xorg-wizardpen/ubuntu YOUR_UBUNTU_VERSION_HERE main Only Natty version and earlier available. Inkscape drawing works but pressure sensitivity does not. But I believe this was also the case in version 11.04. SynfigStudio also works but you must manually install as the Ubuntu Software Center will not install even though it is listed. There appears to be no setup for tablets so again..., no pressure sensitivity capabilities. Regarding Blender..., Drawing OK, all pen buttons work. Pressure sensitivity is supposed to be active in SCULPT MODE but I couldn't get it to work. But this could be due to my ignorance of the proper use of this function. Considering that the BIG BUCK BUNNY project lists the use of SYNFIG STUDIO, BLENDER, GIMP and INKSCAPE as tools , this bug presents itself as a serious problem meriting top priority regarding a fix. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/863154 Title: Wacom Bamboo One tablet random coordinate malfunctions Status in “gimp” package in Ubuntu: Confirmed Bug description: The tablet in overall seems to work correctly, with all pressure- features working.

Confirmed Deevad's findings with version 2.7.3xx nightly build PPA in Ubuntu 11.10 386 ver. but using Genius Mousepad 8x6 tablet in our case. See Post #12: Getting same output as your Wacoms. "Gimp 2.7.3+Git compiled from source with Gimp-razor... seams to not suffer of this, but it really slow and got some 'missed strokes' or 'empty strokes' ( you paint , and nothing appear, as if the brush engine get freezed )." Exactly, the spontaneous streaking to the edge of the canvas is no more. But if you draw fast you get holes in the lines you draw as if the signal from the tablet was being dropped or interrupted for a small fraction of a second. If you draw slower, it's not a problem. Confirmed Matthew Meyers findings in post #40: "however as 2.7.3 won't install on 64bit systems" GIMP 2.7.3 would not install on our 64bit Ubuntu 11.10 setup. In contrast to these problems with GIMP, MyPaint works flawlessly with the Genius tablet with no setups required and full pressure sensitivity. @Deevad: Thank you for the reference to davidrevoy.com. Excellent program/utility selections and setup info. My daughter is the graphics artist wannabe. I'm just trying to bug swat things before I turn her loose on attempting to learn this stuff. Learning is much more difficult in a buggy environment because when something goes wrong you don't know whether it's you or the programming. And, that causes fear and apprehension which inhibits learning. It's obvious to me that I should go to Walmart and buy a couple of 16GB Sandisk Flash drives to install bootable Linux variations to see what setups give the least aggravations.

[Desktop-packages] [Bug 863154] Re: Wacom Bamboo One tablet random coordinate malfunctions
Confirmed Diggao's post #11. Line streaking/spiking was produced in GIMP 2.6 using only a standard generic Microsoft Optical Mouse (USB-PS/2 Compatible) and Ubuntu 11.10. Nothing like this seen in other programs such as MyPaint, SynfigStudio, Inkscape or Blender. In fact, the streaking frequency was far more prevalent, 5 to 10 times greater, with the mouse than the Genius Mousepad 8x6 Tablet on our 64bit Ubuntu setup. Did the same thing with a Dell ball-tracking mouse with PS/2 connection on our 32bit Ubuntu setup. I can't help but think that maybe someone made some little tweak in communication protocol and loused up the connection handshaking from what was previously agreed upon. Or maybe another few clock cycles were added in some other process that causes a loss of communication which must be then reestablished. Maybe the line streaks in GIMP 2.6 are the same thing as the dropouts you get the faster you draw in GIMP 2.7.3. Perhaps they are the same problem manifest differently. The problem is across multiple hardware peripheral devices proven to work before the upgrade to 11.10. So it's not the hardware or their drivers. It has to be the way information is passed to and from GIMP to the Kernel. The compatibility problem is probably in the new kernel. It would be interesting to find another debian based distro with the same kernel to see if the problem can be reproduced. Or maybe it is that compounded with a buggy Compiz. Deevad may be correct about a buggy Compiz and Xorg. "Compiz is one of the first compositing window managers for the X Window System that uses 3D graphics hardware to create fast compositing desktop effects for window management. The effects, such as a minimization effect and a cube workspace are implemented as loadable plugins. Because it conforms to the Inter-Client Communication Conventions Manual standard, Compiz can substitute for the default Mutter in GNOME or KWin in KDE." >From http://www.davidrevoy.com/index.php?article95/linux-mint-11 -install-notes "Correct distribution bugs : Linux Mint 11 comes with all the bugs of Ubuntu 11.04 Natty Narval .
