Mouse cursor goes invisible after return from suspend

Just noticed I didn't mention what graphics chip this bug is experienced on;

VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

So the rest of the screen still comes back fine, it's just the mouse-cursor that fails to display.

What happens if you switch to a virtual console and then back again (Ctrl-Alt-F1 Alt-F7) ?

Yes, everything looks good except the invisible cursor. Switching to console and back does not help.

I can confirm this. A temporary fix would be to turn on swcursor in xorg.conf, hopefully a real fix will come along!

Further investigation shows that this only happens with 24 bit depth. The problem does not show up when using 16 bits. Also - suspending is not needed for the cursor to disapear. Switching to a console and back is sufficient.

Unfortunately both swcursor and 16 bit colordepth makes compiz unusable.

I found that with my dell latitude d505 by flashing the bios to version A09 (10 and 11 caused errors), and changing the uma to 8mb the issue was solved.

I have just upgraded my bios to A09. But what is the uma, and how do you change it?

When entering your bios setup (<F2> on boot), the UMA size settings will be found on page three in your bios config dialog. (<ALT>+<P> switches between pages).

The UMA stands for Unified Memory Architecture, and is the memory which the bios reserves for the graphics by default.

Thats where I thought it'd be. Unfortunately there is no mention of UMA on any of the pages in the BIOS on my machine. This must be different across the different Dell models, so I guess I'm still stuck with the disapearing cursor bug :(

It appears on Feisty this bug is fixed. At least, I don't have any problems anymore running the latest versions.

Thanks for the update! Closing the bug.

This is happening on my system with Lynx. However, my Acer Aspire 5515 has no i810 but some kind of integrated Radeon. Workarounds include: switching to text terminal and back to X (Alt+F1, Alt+F7), locking (Ctrl+Alt+L) and unlocking the screen. If the screen locking when suspending is enabled, then the bug doesn't happen at all.

Also happens to me on Thinkpad z60t.

Mouse cursor disappears after any screen blanking occurs, either by closing lid or suspending. Blanking the screen with xset or vbetool (vbetool dpms off/suspend/standby) does NOT cause the problem.

Switching to text console and back to X (Alt+F1, Alt+F7) fixes, as does starting a movie with mplayer (VLC doesn't do the trick).
