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.

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.

Hi nitram

- 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)

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.

[nitram]

- Motherboard does not have an AGP slot to install different graphic hardware
- Toggled various graphic BIOS settings - no fix
- Changed xorg.conf video resolution - no fix
- Tried more xorg.conf options (eg DRI false, NoAccel true) - no fix
- Attempted to utilize Intel drivers from TC 4 and 5 - failed to boot graphics
- Tried Vesa driver - poor resolution and Openbox performance
- Output of 'cat /proc/mtrr' identical on TC6, Ubuntu 10 and Puppy Slacko 5.7
- Attempted numerous mtrr boot parameters (eg. enable cleanup, spare_reg, various gran_size and chunk_size) - nothing

Thoughts:
- Same performance issue with Intel and Vesa drivers, likely not a driver issue
- None of the mtrr boot parameters helped - maybe not mtrr issue
- Will try Openbox v3.4.11 from TC 4
- Will look into Intel xaa module stuff

Hi nitram

- Output of 'cat /proc/mtrr' identical on TC6, Ubuntu 10 and Puppy Slacko 5.7

Then I doubt it's an MTRR issue. You want to focus on what's different between TC and Ubuntu. See what Ubuntus Xorg log
says about  xaa  as mentioned here:

Code: [Select]

[    56.612] (EE) intel: Failed to load module "xaa" (module does not exist, 0)This message is also of interest:

[nitram]

Thanks again for pointers Rich.

Loading Xorg-7.7-3d.tcz at boot made no difference and the i810 isn't listed in the file list.

Attempted to load my Ubuntu libxaa.so file, which is missing in TC. Saw it but failed, incompatible:

Darn old Intel i810, which has been problematic on various distributions but never like this. Simple fix if the board had a good old fashioned AGP port, got lots of extra cards.

So not an Openbox issue but i'm unclear whether the problem stems from the kernel, Xorg or Intel. Don't really know where to go now. This is getting pretty deep, probably not a quick fix, other than switching WM. Will look at it again later with fresher brain.

[nitram]

Sorry not probably Intel driver either (ruled out with Vesa testing). So either kernel or Xorg i guess.

My xorg.conf if it helps. Maybe need to load modules here with TC ? ....will look into it.

Did you try TC 5.x?

[nitram]

Hi Béla.

Posting from a TC 5.4 test install - same problem. I think TC 5 still uses Xorg 7.7, just different kernel.

Although old versions may pinpoint a regression, in the end i will choose to stay with TC 6. As mentioned, JWM works great on this old hardware with TC 6, despite the xorg log errors, so i can revert back if necessary.

Still wish there was a fix for this hardware issue though, Openbox still my fave.

Will try TC 4 later too and provide update.

[bmarkus]

Hi

you are right, 5.x/4.x just for diagnostic purpose.

Béla

[nitram]

Poor Openbox performance on my hardware in TC 6 and TC 5. Both use the same version of Openbox and Xorg, but have different kernels and Intel drivers. Already ruled out a probable driver issue, as vesa driver also gave poor performance and worse monitor resolution.

Openbox performance in TC 4 is great, using Openbox 3.4.11.1 instead of 3.5.2 and Xorg 7.6 instead of Xorg 7.7...and still different/older kernel. Wish TC 4 had the newer Xorg 7.7 to definitively test. There appear to be significant changes from Xorg 7.6 --> 7.7.

Kernel isn't supposed to have regressions, i'm sure it happens. Was able to get older Openbox 3.4 running in TC 6 by adjusting some minor dependencies but still poor performance.

Suspect a regression occured from Xorg 7.6 --> 7.7. Will copy relevant Xorg 7.6 files into my TC 6 install and see if it works. Otherwise might try running Xvesa vs Xorg for testing, but need to stay with Xorg for higher resolution.

Forgot to check TC 4 xorg log to see if same errors mentioned above - will check.

[nitram]

Xorg log cleaner with Xorg 7.6 on TC 4. Despite outputs, Openbox runs perfect. Software rendering good enough for me, Xorg 7.7 in TC 6 'could not load software renderer'.

[nitram]

Success 

On my old hardware, TC 6, latest Openbox 3.5 works great with Xorg 7.6 and Intel driver from TC 4 plus driver pathway tweaking.

Still head scratching. IIRC, an original Xorg error from stock TC 6, running latest Xorg 7.7 with Intel:

Code: [Select]

[    58.720] (EE) AIGLX error: dlopen of /usr/local/lib/dri/swrast_dri.so failed (/usr/local/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory)
[    58.720] (EE) GLX: could not load software rendererQuery an Xorg or driver bug, as i believe this file was actually located in /usr/local/lib/X11/modules/dri. Will try stock TC 6 again to try and confirm.

Edit/add: The i810 Intel driver in TC 4 with Xorg 7.6 was also in the wrong pathway. Once corrected, every Xorg log error disappeared and hardware rendering was enabled.
