VESA 2.3 (from Xorg server 1.7.6) excrutiatingly slow

Post by monnier »

The VESA driver from Debian testing is incredibly slow (I get to see in which order my windows are drawn when switching desktop). Now, I know that VESA is not accelerated, but this is much worse. The VESA driver from Debian stable (from Xorg server 1.4.2) is *much* faster (as in "quite usable for everyday coding").
Has anyone seen this or has any idea how I can get back the normal speed (other than by downgrading to Debian stable's driver)?

[I already noticed that the testing driver chooses 32bpp by default whereas stable chooses 16bpp, so I changed my xorg.conf to enforce 16bpp but it did not make a significant difference.]

You may want to try fbdev driver instead of vesa. Others reported it is much faster.

Sorry for not replying earlier, but I tried the fbdev driver and indeed it gave me back the performance I used to use with the earlier vesa driver, so it's a good workaround. Thank you.
