Seems unlikely that this would be specific to UNR, but all the reports I'm seeing for it were reported on UNR. Anyone seeing this on desktop?

 This is the first time I report a problem on Ubuntu Alpha version.

I run it on an ACER d150 0Bk, as i do with Intrepid. I faced no problem of this kind on Intrepid.

That is all I can do. Sorry.

You received this bug notification because you are a direct subscriber
of a duplicate bug.

I have the standard 'desktop' installed and it happened to me, but I suspect it may have something to do with the odd resolutions found on netbooks (like 1024x600)

I can confirm this on a 'desktop' installation. In particular, on a Asus eee 1000 with 1024x600 resolution.

I'm experiencing this bug with a standard desktop installation on an Eee PC 901 with 1024x600 resolution. But maybe it is related to the intel graphics in general and not only to this resolution.

I have what appears to be the same issue on karmic on a Dell Mini 10v which also has a 1024x600 display.

Ok, that's what I was suspecting - seems to be on resolutions of 1024x600 or less. Removing ubuntu-unr tag/subscription since it is not specifically a unr bug. Thanks for the feedback!

Same problem on Asus Eee PC 1000h (1024x600). The bug appears only when the session starts.

I have not seen a usplash boot animation on Karmic yet. I have Dell Vostro A90 (Mini 9) and received this same apport trace.

I'm running Karmic on an Asus 1008HA and get this error on each power-up.

Same problem with Acer Aspire One, as described in the duplicate bug, number 405422

Same on Dell Mini 9.

@Robert Hooker: thanks for the back traces (NB: you're attaching them to a dup now, please attach further info in this main bug. Also note that the printf you commented out seem to cause a different crash.)

The stacktrace in bug #406569 shows:
#3 0x00871096 in usplash_clear (x1=332, y1=457, x2=692, y2=607, colour=0) at libusplash.c:228
while yres is 600. Clearing beyond the screen limits.

This is computed in clear_text() where y2 = y1 + theme->text_height;.

It seems a) our theme crashes on yres < 607 and b) usplash doesn't check screen bounds.

Could someone please test libusplash0 + usplash 0.5.31 from https://launchpad.net/ubuntu/+source/usplash/0.5.31 (click on "jaunty i386" or "jaunty amd64": does that version work for you?

I found various inconsistencies in usplash-theme-ubuntu themes, especially themes where text_y + text_height > theme_height. I discussed this with Kenneth Wimer and he said he will fix the theme.

Please keep in mind some of these crashes are with the Kubuntu theme too.

Indeed it was just a theme problem! I installed the mythbuntu usplash theme instead and it works.

This bug was fixed in the package usplash - 0.5.33

---------------
usplash (0.5.33) karmic; urgency=low

  * Fix return type of strncspn in libusplash.h
  * Include usplash-theme.h from libusplash.h as it uses struct usplash_theme
    in declarations.
  * Include libusplash.h in libusplash.c to ensure sanity of prototypes.
  * Remove duplicate testcard_theme definition from libusplash.c.
  * libusplash.c: drop most prototypes for non-static functions which are
    already declared in libusplash.h.
  * Add usplash_sanity_check_theme() and use it to reject themes which have a
    textbox which overflows the theme dimensions; LP: #401432.
  * Also sanity check progressbar dimension for overflows.

This bug was fixed in the package usplash-theme-ubuntu - 0.24

---------------
usplash-theme-ubuntu (0.24) karmic; urgency=low

  [ Kenneth Wimer ]
  * Correcting text box placement values and resolution for some configs
    entries to fix LP: #401432

Hi Loic

Many thanks
