Bug Description

Binary package hint: xorg

Switching from running xserver to a virtual terminal via CTRL+ALT+Fxx and back causes the system to freeze. When switching back to X a black screen appears. The computer does not react to any keys or acpi buttons and has to be reset. This problem also appears when DRI is turned off or when the vesa driver is used instead of the ATI one. With the vesa driver the system crashes not so often but it still happens after a couple of terminal switches. Instead of a black screen, the screen fades gradually to white when the system freezes and the vesa driver is used.

Changing the kernel to 2.6.32 or using the newest drivers from xorg edgers could not solve the problem. This problem did not appear before with Ubuntu 9.04.

I noticed that lspci reports 256M of memory for my card although I can only select 32,64 and 128M of shared memory in my BIOS

I can confirm the freeze when switching back to X. But it disappeared when upgrading to a newer -ati driver (which we should get in lucid soon) or using xorg-edgers. I used KMS in all cases.

Unfortunately, using KMS makes the system even more unstable for me with freezes. When I switch the resolution inside the X-server and KMS is enabled the screen gets corrupted. I also experience crashes with KMS so I disabled it again.

Hi christian, I might be experiencing the same issue, also with a Radeon Xpress 200M.

However, I could not reproduce using the vesa driver. This might be because the VT's and X used the same resolution (800x600), possibly avoiding triggering the bug. Did you manually set a higher res when using the vesa driver?

Also, can you reproduce the freeze with a suspend/resume cycle? I can.

Since the VESA bug occurs (at least for me) when switching _from_ X instead of _to_ X, I have reported it as a different bug against VESA: bug 502485.
