Public bug reported:
Bug: Mouse cursor/pointer is invisible after an installation and reboot of
Xubuntu i386 14.04.3; 15.04; 15.10 betas and daily image. The same happens
after installation and reboot of Ubuntu i386 15.04 (didn't try other versions).
The mouse is still there because we can see it act on the corner whiskermenu,
and when it passes over the menu entries or the xfce panel icons but it's
invisible, so it's not possible to use the system to report the bug via the
terminal tools. The mouse pointer works perfectly in all the live sessions and
even during installation. It's only after rebooting that the pointer disappears
(trackpad or mouse it's the same).
I was using Linux Mint 17.2 on my work/stable partition but decided to test
Xubuntu on my sda3 test partition and went through all the installations that I
referred above.
I ended up installing Voyager 14.04 (with Xfce 4.12) which is a Xubuntu based,
actually it's the Xubuntu core, with very customized icon/themes, settings,
scripts, conky, etc.
Verified that the bug doesn't occur when installing Xubuntu 14.04 and Xubuntu
14.04.2. But at 14.04.3, then 15.04, then 15.10 the bug is there.
Could it be from the particular hardware configuration I'm using? CPU: Intel
Atom N455 @1.66 Ghz (1 core, 2 threads); RAM: 1 Gb; GPU: Intel GMA 3150
(integrated, shared memory, own memory=64 Mb). This Acer Aspire One 260
notebook is from 2010.
Of course Linux Mint Xfce 32bit 17.1 and 17.2 do not have this bug at all.
Installation is flawless.
And now what I found out: in one installation of Xubuntu 14.04.3 I managed to
get the mouse pointer back by using the reaction to the mouse over in the
Settings menu to go to Mouse and Touchpad settings and there, with a lot of
luck I was able to change the default theme to DMZ Black and got the mouse
pointer back. Of course I forgot to file the bug report (sorry!) because I then
was trying to fix it and installed the oxygen-mouse-cursor, via Synaptic, then
selected oxy-white as default cursor. But the oxy-white cursor only appeared
inside some apps and setting screens, like Firefox, Synaptic, etc. On the
desktop it reverted back to DMZ-Black. I NOTICED that the default mouse CURSOR
PREVIEW, in Mouse & Touchpad settings IS EMPTY, DOES NOT show ANY PREVIEW at
all. Then I discovered that in "/usr/share/icons/default" there is only a
symlink called "index.theme", which contains this text: "[Icon Theme]
Inherits=DMZ-White" and links to "/etc/alternatives/x-cursor-theme", which is
another
(!?) symlink file that links to "/usr/share/icons/DMZ-White/cursor.theme" and
contains the same "[Icon Theme] Inherits=DMZ-White" text. Sorry but isn't this
way of setting the default mouse cursor theme a complete denial of the KISS
principle? And it sure does look like a kludge to me, but then I only use Linux
since May of 2013, so forgive my tone, I'm pretty sure I'm talking about stuff
that I don't understand enough, sorry. And on top of all this, I saw no other
"invisible mouse cursor" bug report in Launchpad, and trust me, I really looked
for it. So I guess this means bad luck for me, I'm the only one affected,
unless other users of Acer Aspire One are newbies and don't submitted the bug
at all. They just changed to Linux Mint when their mouse was gone. By the way I
will now examine how Linux Mint deals with the default mouse problem and will
compare system folders, at least the ones I've mentioned above. So I'll do a
clean install on Linux Mint Xfce 17.2 on my test partition.
I don't know if you're interested in what I might find. It seems that you
deserve a prize just for reading through all this stuff!
Well you have my email: kafsh...@gmail.com and, if something happens to this
bug, I would like to help with it. Many thanks for all that might happen and
don't worry, if it is the hardware's fault I can always use Mint, although I
prefer Xubuntu.
