View Full Version : [SOLVED] Newbie's day-6 question - ThinkVision display

Installed Ubuntu 11.10 several days ago on an IBM ThinkCentre A50P 8432-94U, with the dual-boot option - the master HD has the Windows XP Pro and half of the slave HD, while Ubuntu has the other half of the slave HD (both HDs are WD 300GB disks); used all default installation setting and no tweaks in my part.

Now just discovered that the IBM ThinkVision L170 display shows up in Dash -> Installed -> Display as a pp!France 17" unit, with a 1280x1024 (5:4) resolution setting.

The display seems to work just fine. Just that every time using emacs in a Terminal window, it would produce GTK related warning messages, though emacs functions seem not affected.

I have not used Ubuntu long enough to notice any display problems.

The question is why an IBM ThinkVision L170 display shows up in Ubuntu as a pp!France 17"? Any potential problem with this and what I need to do?

You can ignore the name of the monitor. My LG monitor is also not reported as that but works just fine.
With respect to the terminal error messages there have been reports about these on the forum. I don't know your exact error messages but if Emacs works fine they are most likely just warnings. You could post them here so that we have a look at them.

The message after open emacs looks as the following:

chenxinghao@MyUbuntuSandBox:~$ emacs testpapge

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix
map",

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix
map",

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix
map",

(emacs:5640): Gtk-WARNING **: Unable to locate theme engine in module_path: "pix
map",


The "WARNING" doesn't seem to have effects on emacs functions.

I like to understand the meaning and why they were out every time I use emacs.

Thank you.

As mentioned in your other thread, it is Gtk2/3 compatiblity problem, not anything to do with your monitor.

No GTK warning messages any more - clean emacs at last!

Thanks.
