Yep, I was able to reproduce this X server crash on natty myself. ** Description changed:
I am on Ubuntu 10.10 with the default X server, and the following Python code crashes it every time: from Tkinter import * f=Frame() f.option_add('*font', "-family {DejaVu Sans} -size -25 -weight normal -slant roman -underline 0 -overstrike 0") f.pack() text = StringVar(f) entry = Entry(f, textvariable=text) entry.pack() text.set("a" * 600) f.mainloop() Unfortunately, I was not able to capture a backtrace with apport. I'm using an Asus X58Lseries laptop which I believe is 1280 x 800 (WXGA) using an Intel GMA X3100 graphics chipset. I have set System > Preferences > Appearance > Fonts > Details > Resolution to 160 DPI for a larger display. + + Backtrace: + [ 30015.409] 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80eaa9b] + [ 30015.409] 1: /usr/bin/X (0x8048000+0x5faa8) [0x80a7aa8] + [ 30015.409] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0x4c140c] + [ 30015.409] 3: /usr/lib/xorg/modules/drivers/intel_drv.so (0x8e4000+0x1e98a) [0x90298a] + [ 30015.409] 4: /usr/lib/xorg/modules/drivers/intel_drv.so (0x8e4000+0x28700) [0x90c700] + [ 30015.409] 5: /usr/bin/X (0x8048000+0xdff88) [0x8127f88] + [ 30015.409] 6: /usr/bin/X (CompositeGlyphs+0xb0) [0x81c4e40] + [ 30015.409] 7: /usr/bin/X (0x8048000+0xd9373) [0x8121373] + [ 30015.409] 8: /usr/bin/X (0x8048000+0xd5153) [0x811d153] + [ 30015.409] 9: /usr/bin/X (0x8048000+0x28127) [0x8070127] + [ 30015.410] 10: /usr/bin/X (0x8048000+0x1a7ec) [0x80627ec] + [ 30015.410] 11: /lib/i386-linux-gnu/libc.so.6 (__libc_start_main+0xe7) [0x296e37] + [ 30015.410] 12: /usr/bin/X (0x8048000+0x1a3e1) [0x80623e1] + [ 30015.410] Segmentation fault at address 0xc + [ 30015.410] + Caught signal 11 (Segmentation fault).
