I'm using ati-drivers-10.7 with xorg-server-1.7.7-r1. No special settings |
8 |
in xorg.conf. I never had much success with the open source radeon |
9 |
drivers. First they did not run at all, I either did not get X started, or |
10 |
I only got a blank screen. One month ago then I had success with xf86- |
11 |
video-ati-6.13.1, but X crashed instantly when I moved the mouse cursor |
12 |
onto the KDE panel. But now I have a new KDe version, so I wil give them a |
13 |
try soon. |

Wow, at the moment X takes 95%. When I disable desktop effects, it's down |
16 |
to 5%. When enable desktop effects again, X uses 60%. |
17 |
|
18 |
Now I went into systemsettings -> desktop effects -> all effects, and |
19 |
played around with the individual settings. When I disable the blur effect |
20 |
(two lines after transparency), X usage is at less than 20%. Weird, I do |
21 |
not even see any difference this effect makes. Cool, much less X usage by |
22 |
disabling something I did not even notice :) |
23 |
|
24 |
Is 15-25% X usage still too much? I have several plasmoids running, so I'm |
25 |
not surprised this eats some performance. BTW, at [*] there are some |
26 |
screenshots of my desktop, which did not change much since I did the |
27 |
screenshots. |

The system already feels better now. But this cannot be the only problem, |
30 |
I sometimes (especially during large emerges) turn desktop effects off, |
31 |
and when I have too much load, they are turned off automatically. |

Damn right. I used to have less memory, and ran very memory-intensive |
37 |
applications, and the system was much more responsive than now. |
