[Ubuntu-x-swat] [Bug 532137]
I quickly looked at the Xorg.log files from launchpad below. Right after hotplug of tablet, usbParse() goes in infinite loop and prints message about invalid serial #. Not positive its infinite loop but at least the log stops with no messages beyond repeating error message. If you wait long enough, perhaps the tablet corrects itself? Intuos1 and Intuos2 are unique in that they get serial # from hardware itself and used by xf86-input.wacom. Serial # is a unique value that allows tracking multiple tools at once. You've found a case were tablet streams out packets in a way that serial # is sent as zero. Either tablet is saying a zero value or else an if() statement is getting confused and not allowing to init values correctly. This is all on kernel side, BTW. Since I do not own own of these tablets, I do not have much more to offer. I can only say it appears mostly a kernel side bug from information so far.

I reviewed the other patchwork patches just now. Patch 6209 in Comment 7 addresses panning part of issue in crtc_bounds() using same logic from ProcRRGetCrtcInfo(). If you combine my modification from Comment 17 with the patch 6209 then you'll get solution for both scaling and panning. Not sure its the right solution and it seems a little excessive to compute each X/Y movement... but I hope it helps move us along to final solution. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/883319 Title: xrandr --scale restricts area in which mouse moves To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/883319/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 883319]
I use xrandr for scaling to make a small netbook screen able to display
apps that don't fit in 1024x600 and noticed this regression over the
last year in 1.11. I finally decided to look closer since 1.12 didn't
seem to fix the issue and came across this report.
I looked at the revert commit to get idea of area that could possibly be
fixed and it seems like crtc_bounds() is probably a function that should
be returning a value related to panning/scaling.
I traced were xrandr output is querying the panning/scaling values it
displays and looks like comes from ProcRRGetCrtcInfo() and that function
makes use of RRCrtcGetScanoutSize() to scaling width/height to correct
size. Panning uses rrGetPanning().
To test the idea, I modified crtc_bounds to handle scaling case by
adding ProcRRGetCrtcInfo() call. It does seem to work and I've not
noticed a negative in limitted testing.
I patched a source RPM so I can't offer a real patch right now but here
is my modified version of function to get an idea:
static void
crtc_bounds(RRCrtcPtr crtc, int *left, int *right, int *top, int *bottom)
{
int width, height;
RRCrtcGetScanoutSize (crtc, &width, &height);
*left = crtc->x;
*top = crtc->y;
switch (crtc->rotation) {
case RR_Rotate_0:
case RR_Rotate_180:
default:
*right = crtc->x + width;
*bottom = crtc->y + height;
return;
case RR_Rotate_90:
case RR_Rotate_270:
*right = crtc->x + height;
*bottom = crtc->y + width;
return;
}
}

[Ubuntu-x-swat] [Bug 854445] Re: Asus ep121 (eee slate) touchscreen not working
The discussion then moved over to linux-input mailing list were it got fully resolved by hid-multitouch developer. A fix will be in Linux 3.3 (its in a hid next branch). The fix is slightly larger than adding new product ID's to hid-multitouch. The touchscreen uses a "MT serial" protocol that happened to be added to hid-multitouch for another touchscreen in November timeframe as well. This version of eGalax touchscreen makes use of that new feature in hid-multitouch. This issue is pure kernel side issue and nothing to change in xf86 -input-evdev if you want to reassign bug report. If your interested in more why xf86-input-evdev was acting strange with HW you can look at thread in comment #4. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/854445 Title: Asus ep121 (eee slate) touchscreen not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/854445/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
