Tiny Core Extensions > TCE Q&A Forum
Xorg 7.7 appears to affect Openbox performance with intel i810 graphics...
nitram:
Tweaked JWM, but still prefer Openbox.
Running TC 6.2, extensions updated, old hardware (800 Mhz, 512 MB ram). Intel i810 onboard graphic chip is supported by the TC Intel driver. JWM performance in TC is awesome. Openbox performance is also good on the same hardware running Ubuntu 10.04, Openbox v3.4 (TC 6 uses v3.5), same xorg.conf file with only 16 colour depth.
Openbox issues in TC:
- Very slow performance when resizing windows (stutters when sizing, like a slideshow)
- Very slow performance when dragging windows (eg. takes 5-10 seconds to drag Apps window across 1152x768 screen, visible stepping of window borders and window signicantly lags behind mouse cursor)
Already tried toggling various xorg.conf graphic options without success (eg. NoAccel, DRI). Was apparently able to successfully compile Openbox v3.5 from source but system booted without a cursor (don't ask me, still learning how to compile, error free though).
The only console error i see when running Openbox is 'obt-message: Zinerama extension is not present on the server'. Only similar extension found in Apps was libXinerama, which i loaded/rebooted - no difference.
Openbox performance is otherwise good when opening menus, opening/closing apps, etc. Unfortunately the issues described above make it practically unusable. Never experienced this with a window manager before. Driving me crazy. Hints appreciated.

nitram:
Still troubleshooting with no success.
- Disabled background image - no fix.
- Killed conky - no fix.
- Changed dpi via .Xdefaults from 96 to 128, rebooted - no fix.
As mentioned, my old Ubuntu used Openbox 3.4.10 vs TC 3.5.
Forgot to mention, my old Ubuntu install uses the 2.6 kernel.

See if any information is showing up in /tmp/wm_errors after performing those actions.
Also check for warnings and errors in /var/log/Xorg.0.log.
Also see if any new messages show up in dmesg.
nitram:
Thanks for the help Rich.
Updated TC 6.2 to 6.3rc2, rebooted, no Apps updates, updated .dep files, build reporting database, no missing dependencies.
Rebooted with 'base text norestore' options, manually loaded xf86-video-intel, Xorg, Xprogs, aterm and openbox - same problem.

Will investigate errors as best i can, starting with 'performance may suffer' dmesg stuff and module xaa fail. May try an archived Intel driver. Never had much luck deciphering logs, if anyone sees something please let me know.

I'd probably try looking into that first. Run:
--- Code: ---cat /proc/mtrr
--- End code ---
Compare the results for that under TC and Ubuntu. This may also be of use:
