Comment 9 for bug 1851340

Thanks for the tip - now that we know we have the same graphics chip, it's obviously a G200 driver issue. Looking at the kernel history, we find:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=574cc4539762561d96b456dbc0544d8898bd4c6e

which includes:

mgag200:
   - cursor support fix

Which would suggest that this has since been fixed upstream, and it's just a matter of time until it hits the ubuntu repositories.
