Hello Timo, Thanks for reporting and debugging this issue. I have just adopted the package but I still need to setup a test environment and else.
Anyway, could you please rebuild and test with the following patch which basically has two upstream patches which fixes: From: Grazvydas Ignotas <[email protected]> at least xserver 1.7.4 crashes on XGetPointerControl request because of xf86-input-tslib: Program received signal SIGSEGV, Segmentation fault. #0 0x000355e0 in ProcGetPointerControl (client=0x4a2e58) at devices.c:2122 #1 0x00062fa8 in Dispatch () at dispatch.c:439 #2 0x00022444 in main (argc=4, argv=0xbeebedc4, envp=0xbeebedd8) at main.c:285 This happens because ptrfeed field is not set in device structure from tslib. To fix this, call InitPtrFeedbackClassDeviceStruct() during DEVICE_INIT to get necessary setup done (as done in other input drivers). -- From: Stanislav Brabec <[email protected]> Subject: xf86-input-tslib-0.0.6 crash fix with xorg-server-1.7.3 Here is a fix for crash of xf86-input-tslib-0.0.6 with xorg-server-1.7.3 that should be backward compatible. xorg-server-1.7.3/hw/xfree86/common/xf86Helper.c contains this code causing a double free crash on chvt or exit: /* This should *really* be handled in drv->UnInit(dev) call instead, but * if the driver forgets about it make sure we free it or at least crash * with flying colors */ if (pInp->private) xfree(pInp->private); PATCH: Index: src/tslib.c =================================================================== --- src/tslib.c (revision 46) +++ src/tslib.c (revision 48) @@ -103,8 +103,6 @@ static void PointerControlProc(DeviceIntPtr dev, PtrCtrl * ctrl) { - ErrorF("%s\n", __FUNCTION__); - return; } static Bool @@ -406,6 +404,8 @@ xf86MotionHistoryAllocate(pInfo); #endif + if (!InitPtrFeedbackClassDeviceStruct(device, PointerControlProc)) + return !Success; break; case DEVICE_ON: @@ -435,6 +435,7 @@ xf86TslibControlProc(pInfo->dev, DEVICE_OFF); ts_close(priv->ts); xfree(pInfo->private); + pInfo->private = NULL; xf86DeleteInput(pInfo, 0); } Cheers, -- Héctor Orón "Our Sun unleashes tremendous flares expelling hot gas into the Solar System, which one day will disconnect us."
