already fixed in intrepid with 1.2.1.
** Description changed:
- Binary package hint: qemu
+ The cirrus driver advertises supported depths wrongly, for e.g. the
+ cirrus gd5446, telling that the cards would unconditionally support
+ 32bpp. However this is not the case for the 5446 and the 5430. Hence
+ autoconfigured X won't start with this graphics cards. In previous
+ ubuntu releases, this was no problem, since the default depth was set to
+ 24bpp, however hardy defaults to 32bpp. At a later point, the driver
+ correctly fails to set the max value of the pixel clock, since this is
+ indeed conditioned on the given graphics adapter.
- Testing hardy alpha4 live cd.
+ The proposed patch is taken from the intrepid package (1.2.1), which
+ conditionally advertises the capabilities based on the detected graphics
+ card.
- system boots up okay, without dropping to initramfs. However Xorg fails
- to start.
+ Impact: regressing since gutsy, for everyone with a gd5446 (won't be too
+ many I assume, since it's an old graphics adaptor). Additionally anyone
+ trying the live cd in a vm which simulates the gd5446 (e.g. qemu).
+
+ TEST CASE: boot hardy live cd on a box (or vm) with a gd5446. X won't start.
install the new driver right into the livefs and try to start X. Works.
+ vm's you can use for testing: qemu or FAUmachine (not packaged), which both
come with different implementations of the gd5446.
+ kvm (which also uses the gd5446 from qemu) is not affected, since dexconf
detects the kvm instance and sets the default depth to 24bpp.
