[Bug 432350] New: SaX2 connects to wrong port on Thinkpad X60 MultiTouch tablet
https://bugzilla.novell.com/show_bug.cgi?id=432350 Summary: SaX2 connects to wrong port on Thinkpad X60 MultiTouch tablet Product: openSUSE 11.1 Version: Beta 1 Platform: PC OS/Version: SuSE Other Status: NEW Severity: Normal Priority: P5 - None Component: SaX2 AssignedTo: sndirsch@novell.com ReportedBy: carlos.lange@ualberta.ca QAContact: sax2-maintainer-bugs@forge.provo.novell.com CC: dkukawka@novell.com Found By: --- SaX2 assumes the Wacom tablet/touchscreen from X60 Multitouch is associated with ttyS0 and writes xorg.conf accordingly. This causes the boot process to freeze while initializing X showing just the x pointer frozen in the middle of the screen. But the output of setserial -g /dev/ttyS* below (obtained by activating the tablet, but not the pen, eraser or touch) shows that the device is associated with ttyS4 in the case of openSUSE 11.1b1: /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3 /dev/ttyS4, UART: undefined, Port: 0x0200, IRQ: 5 /dev/ttyS5, UART: unknown, Port: 0x0000, IRQ: 0 /dev/ttyS6, UART: unknown, Port: 0x0000, IRQ: 0 /dev/ttyS7, UART: unknown, Port: 0x0000, IRQ: 0 and the association has been always with this port at every instance. When xorg.conf is modified replacing ttyS0 by ttyS4 in all 4 sessions (wacom, pen, eraser, touch), then the tablet mode and touch screen mode work fine. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

.. AFAIK there is *no* magic available in SaX2 to default to the right device. It was just luck that the default works for you up to now. There are no features planned for SaX2. Making ttyS4 as default would be wrong as well. If I understood Bug #323541 correctly, ttyS4 is consistenly used only on this machine.

you have to _select_ lenovo x61tablet from the list, so, as ttyS4 is the default for that machine, what could go wrong ?

Since you can't be sure that it's always ttyS4 it would break other machines (e.g. if they have no or a disabled IR port ...). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

At the same time, we should reopen Bug 435581 and treat it as a SaX2 bug, as long as it breaks the test of any port other than the correct one. How is the new user supposed to find the correct port, if any test of a wrong port makes Xorg hang without possibility of restart (Ctrl+Alt+Bksp does not work)? If we save xorg.conf without testing, then the boot process hangs. An acceptable behaviour would be simply the tablet mode not working, while the correct port is not found. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
