On Ubuntu Maverick 32-bit, Ubuntu Natty 64-bit and Debian Squeeze 64-bit the mouse wheel doesn't work. It's ok for older Ubuntu and Debian installs, but those aren't installed any more, just old openSUSE 11.2 64-bit still is on my computer and there the mouse wheel still and always is ok. Sometimes the mouse wheel randomly works for those Ubuntus and the Debian install, but this happens very seldom.
It's not related to the usage of a xorg.conf, this happens with or without a xorg.conf, at least I tested this for Debian. For Ubuntu Natty and Debian stable I tried this (see http://www.larsen-b.com/Article/341.html ). # apt-get update # apt-get install xserver-xorg-input-kbd xserver-xorg-input-mouse And to /etc/X11/xorg.conf I added Section "ServerFlags" Option "AutoAddDevices" "False" Option "AllowEmptyInput" "False" EndSection but this didn't change anything. Then I removed the xorg.conf from Debian stable, to ensure that it's not xorg.conf related, but the issue didn't disappear. On Ubuntu Natty I edited .................................. $ cat /etc/hal/fdi/policy/*.fdi <?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- --> <!-- Some examples how to use hal fdi files for system preferences You can either uncomment the examples here or put them in a seperate .fdi file. --> <deviceinfo version="0.2"> <!-- The following shows how to hint gnome-volume-manager and other programs that honor the storage.automount_enabled_hint to not mount non-removable media. --> <!-- <device> <match key="storage.hotpluggable" bool="false"> <match key="storage.removable" bool="false"> <merge key="storage.automount_enabled_hint" type="bool">false</merge> </match> </match> </device> --> </deviceinfo> .............................. to ....................... $ cat /etc/hal/fdi/policy/*.fdi <?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- --> <!-- Some examples how to use hal fdi files for system preferences You can either uncomment the examples here or put them in a seperate .fdi file. --> <deviceinfo version="0.2"> <!-- The following shows how to hint gnome-volume-manager and other programs that honor the storage.automount_enabled_hint to not mount non-removable media. --> <!-- <device> <match key="storage.hotpluggable" bool="false"> <match key="storage.removable" bool="false"> <merge key="storage.automount_enabled_hint" type="bool">false</merge> </match> </match> </device> --> </deviceinfo> <device> <match key="info.capabilities" contains="input.mouse"> <merge key="input.x11_options.Buttons" type="string">5</merge> <merge key="input.x11_options.Emulate3Buttons" type="string">on</merge> <merge key="input.x11_options.EmulateWheel" type="string">on</merge> <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge> <merge key="input.x11_options.XAxisMapping" type="string">6 7</merge> <merge key="input.x11_options.YAxisMapping" type="string">4 5</merge> <merge key="input.x11_options.ZAxisMapping" type="string">4 5</merge> </match> </device> .............................. and command out the server flags and any mouse entry too from xorg.conf. # apt-get remove xserver-xorg-input-kbd xserver-xorg-input-mouse [snip] Removing xserver-xorg-input-all ...

Rebooting Natty for the first time the mouse wheel did work. Rebooting Natty for the second and any additional time the mouse wheel didn't work anymore. For the moment I let this issue rest and try to fix other debianoid issues on my machine. Again, for older installs of Ubuntu and Debian there never was such an issue for the mouse wheel. I don't know how it is for the current Suse release. The Suse release on my machine is ok for the mouse wheel, but as mentioned before, 11.2 is an outdated release. hwinfo (at Natty) mouse 41: ADB 00.0: 10502 Bus Mouse [Created at input.183] UDI: /org/freedesktop/Hal/devices/computer_logicaldev_input_1 Unique ID: kZYT.VdKNesd9pT6 Hardware Class: mouse Model: "Macintosh mouse button emulation" Vendor: 0x0001 Device: 0x0001 "Macintosh mouse button emulation" Compatible to: int 0x0210 0x0003 Device File: /dev/input/mice (/dev/input/mouse0) Device Files: /dev/input/mice, /dev/input/mouse0, /dev/input/event2 Device Number: char 13:63 (char 13:32) Driver Info #0: Buttons: 3 Wheels: 0 XFree86 Protocol: explorerps/2 GPM Protocol: exps2 Config Status: cfg=new, avail=yes, need=no, active=unknown 43: PS/2 00.0: 10500 PS/2 Mouse [Created at input.183] UDI: /org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port_logicaldev_input Unique ID: AH6Q.U5GX9Ignjc0 Hardware Class: mouse Model: "PS/2 Generic Mouse" Vendor: 0x0002 Device: 0x0001 "PS/2 Generic Mouse" Compatible to: int 0x0210 0x0003 Device File: /dev/input/mice (/dev/input/mouse1) Device Files: /dev/input/mice, /dev/input/mouse1, /dev/input/event4, /dev/input/by-path/platform-i8042-serio-1-event-mouse, /dev/input/by-path/platform-i8042-serio-1-mouse Device Number: char 13:63 (char 13:33) Driver Info #0: Buttons: 3 Wheels: 0 XFree86 Protocol: explorerps/2 GPM Protocol: exps2 Config Status: cfg=new, avail=yes, need=no, active=unknown BUS MOUSE?????????????????????????????????????? mobo ASUS M2A-VM HDMI cpu Model: 15.107.2 "AMD Athlon(tm) X2 Dual Core Processor BE-2350" Clock: 2100 MHz memory Memory Size: 3 GB + 768 MB ? should be 4 GB sound Model: "Xilinx RME Hammerfall DSP MADI" new, untested, it's a HDSPe AIO Model: "TERRATEC EWX 24/96" old cards Model: "TERRATEC EWX 24/96" gfxcard Model: "nVidia GeForce 7300 SE" Resp. it's a 7200 GS disc Model: "SAMSUNG HD321KJ" Model: "SAMSUNG HD502HJ" -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
