Not sure if I selected the correct topics for this issue but here we go.
Environment:
-
OS: RedHat Enterprise Linux 7.9 (Maipo)
-
Kernel: 3.10.0-1160.125.1
-
X.org Server: 1.20.4
-
Touch Driver: PenMount 6000 RS-232 (PenMount-RHEL_CentOS-7.0-7.6-32-64-bit-driver-V4.6.5)
-
Video Driver: NVIDIA Linux x64 (AMD64/EM64T) Display Driver 550.142
-
Disp Monitor: General Digital 3240-062-97-3
-
Video Card: NVIDIA Quadro T1000
What I noticed is that the combination of the NVIDIA (video) and PenMount (touch) drivers, upon a touch input to the monitor screen, the X Server crashes and brings the operator back to the login screen. Inspecting the OS log files points to the following error:
-
Program terminated with Signal 11, Segmentation Fault (SIGSEGV)
-
#0 0x00007f171f1948b1 in pmX11_GetCrtcRotation () from /usr/lib64/xorg/modules/input/penmount_drv.so
I tried reaching out to the PenMount team (Taiwan-based), but no response. Wanted to see if the NVIDIA community could help with this.
