The test setup:
- GForce2MX
- Samsung Syncmaster 940B (a 19" tft)
- Logitech MX500 mouse on USB.
I consider my setup not that exotic, but there are some problems with the xorg.conf that grml-x generates:
*) The frequency for tft's should be 60Hz. I have to run grml-x with the option -hsync 60-60, don't know if it's possible to have this detected automatically.
What does 'hwinfo --monitor' say?
hmm, i can see the problem:
root@grml ~ # hwinfo --monitor 32: None 00.0: 10000 Monitor [Created at monitor.93] Unique ID: rdCR.QTfKIX4qyo3 Hardware Class: monitor Model: "SAMSUNG SyncMaster" Vendor: SAM "SAMSUNG" Device: eisa 0x01ba "SyncMaster" Serial ID: "HMEYC00964" Resolution: 720x400@70Hz Resolution: 640x480@60Hz Resolution: 640x480@67Hz Resolution: 640x480@72Hz Resolution: 640x480@75Hz Resolution: 800x600@56Hz Resolution: 800x600@60Hz Resolution: 800x600@72Hz Resolution: 800x600@75Hz Resolution: 832x624@75Hz Resolution: 1024x768@60Hz Resolution: 1024x768@70Hz Resolution: 1024x768@75Hz Resolution: 1280x1024@75Hz Resolution: 1280x1024@60Hz Resolution: 1280x960@60Hz Resolution: 1152x864@75Hz Size: 376x301 mm Driver Info #0: Max. Resolution: 1280x1024 Vert. Sync Range: 56-75 Hz Hor. Sync Range: 30-81 kHz Bandwidth: 108 MHz Config Status: cfg=new, avail=yes, need=no, active=unknown
With that info it's not possible to know that 1280x1024@60Hz should be used i guess. This values from hwinfo end up in the xorg.conf and the tft compains.
*) I get 2 Entries for mouse in the xorg.conf One "USB Mouse" and one "PS/2 Mouse". This would not be that bad actually, but both use device /dev/input/mice, resulting in a unusable x (double mouse speed and every klick being a double klick)
grmlx -nops2 ...
Well yeah, this does remove the entry.
But there still is the fact that both usb and ps/2 mice and propably all other mice too are accessed by /dev/input/mice so doubt that a xorg.conf should be created that put a pointer on the same device more than once.
Actually i'm quite confused now, because i just found out that if i do a cat on /dev/input/psaux and /dev/input/mouse0 and /dev/input/mice i always get data, no matter if i connect the mouse on ps/2 or usb. I actually didn't expect to get data on psaux when i plug in on usb!
Really weird...
