Hi everybody, I've been using Gnome Shell for a long time know. My Laptop is a Lenovo T420s, which comes with an integrated HD3000 Sandy Bridge (SNB) graphic adapter and a i5 2520 CPU.
Lately, the performance of the Shell has increased and going to activities is smooth, compared to old times where SNB was performing awful. However, after some time the scaling effect "gets corrupted" and slows down. It seems like less frames are shown and going to the activity view becomes a frustrating experience, hurting my concentration. This happens even if I don't use the laptop and leave it idle. I've tried many combinations of software to see if something solved it. More particularly, I've tried all the possible combinations between (running Arch Linux, if that matetrs): Kernel 3.0.x (where x was the stable minor version at different points in time) Kernel 3.1.rcx Kernel 3.1.0 Mesa 7.10.4 Mesa 7.11.0 Mesa from the master tree as of last week (and some other older snapshots) xf86-video-intel 2.15 xf86-video-intel 2.16 xf86-video-intel from the master tree as of last week No combinations were found to work reliably after some time. In particular, if I leave the laptop idle without screen-lock or suspend enabled, when I come back the shell is slower than when I left. Is this a known behaviour. Does anyone else see this on Sandy Bridge equipped laptops or is it only me? Last, but more important, how can I help debugging this? I've got no idea about which logs might be useful: memory and CPU are under control both when animations are fluid and when they are "corrupted". I am enclosing my lspci as a starting point: alessandro at alessandro-thinky in ~ $ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series Chipset Family MEI Controller #1 (rev 04) 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation 6 Series Chipset Family High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 1 (rev b4) 00:1c.1 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 2 (rev b4) 00:1c.3 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 4 (rev b4) 00:1c.4 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 5 (rev b4) 00:1d.0 USB Controller: Intel Corporation 6 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation 6 Series Chipset Family LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 6 Series Chipset Family 6 port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation 6 Series Chipset Family SMBus Controller (rev 04) 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 2c) 05:00.0 System peripheral: Ricoh Co Ltd Device e823 (rev 04) 0d:00.0 USB Controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) Thanks to anybody who has even the slightest idea on what is going on.
