moved to linux kernel package, which contains the modesetting
** Package changed: xserver-xorg-video-ati (Ubuntu) => linux (Ubuntu)
** Tags added: apport-collected precise
** Description changed:
I recenty started to migrate from Lucid (10.04) to Precise (12.04).
Unfortunately, I have noticed that the video rendering performance has
decreased with Precise. Videos with a resolution of about 720x576 that are
played smoothly on Lucid are either flickering or shortly hanging in-between
while played on Precise (the standard video player tends more to flickering, in
vlc I get hangs).
I should mention that I have a quite old graphics card, it is identified by
the X server as
Chipset: "ATI Radeon VE/7000 QY (AGP/PCI)" (ChipID = 0x5159)
After experimenting around quite a while I found out that I get back the
old performance if I boot with "nomodeset", so I guess there's a bug in
kernel modesetting.
BTW, the output of "uname -a" is
