Xorg Wizard: 24-bit depth only

August 31, 2010 — BarryK
I am planning to remove the choice of 16-bit or 24-bit color depth in Xorg Wizard, and choose 24-bit only.

This is one less thing to decide. However, my main reason is that gmplayer does not work at 16-bit color depth -- I previously thought that this was also a JWM problem, but have found it is the same, get black windows in other window managers also.

JWM did have some problems awhile back with 16 versus 24 bit depth, but the latest version has fixed that.

If anyone has a reason for the Xorg Wizard to continue to offer a choice, please respond.


foxit needs 24-bit, FlSynclient error

foxitreader also needs 24-bit (crash on 16-bit) Also... Just tried to open FlSynclient, error Can't access shared memory area. SHMconfig disabled? What does that mean? Known error?

"This leaves me wondering whether this distro wouldn't be following a frequent trend claiming to be progressive, no doubt,and treading a path to its own demise? An unscientific analysis of what folks are actually using Puppy for on the Forum, not just the most voluble from that certain nation, is to liberate yesteryears' HW from an early and untimely crushing. That is the strength of the compact distros. In those instances, the acid test might be: does it run 640x 480 on a 4Mb PCI video card - or at all? Of course there's VESA, but that has had its own uncertainties and issue in recent years. If ever there was a time for navel gazing, this must be it? Is 'retro' the new tomorrow?! Truly a watershed.

16-bit necessity

"Barry, Please keep the 16-bit depth in Xorg Wizard. It allows my P3 i815 box to drive a 1920x1080 monitor at full resolution, something that Intel's Windows XP video driver is incapable of doing! I suspect the 915 resolution hack permitted this amazing occurrence. Currently running on Luci 219, multi-session live cdrw. Previously on Puppy 4.30 (

24-bit vs 24-bit
Username: gjuhasz
"Some video cards report 32-bit capability as 24-bit. In this case, xorgwizard displays two 24-bit options and the user can select between the real 24-bit or the 32-bit resolution (and 16-bit, too). In this aspect, depth selection should remain the user's choice with the highest as the default.

"broomdodger The 'Can't access shared memory area. SHMconfig disabled?' message is not an error as such. if you manage to find the documentation for synclient (on which flsynclient is based) it will tell you that SHMconfig has to be enabled for it to work. If you have a manually configured xorg.conf in use then SHMconfig should be defined as enabled in it somewhere for flsynclient to work. Not sure what happens when Xorg is configuring automatically.

the 16bit option is essential

"A lot of P3 era machines have been upgraded to 17 or 19 inch LCD monitors, but they can only run the native 1280x1024 resolution at 16bit. Similarly, sometimes they can run the native resolution at 24bit, but the picture becomes blurry or they only have hardware acceleration at 16 bit.

pls keep 16 bit

"On the OLPC XO-1 laptop 24 bit produces a flickering screen while gmplayer gives a black window on playback. This may be related to server configuration and/or the geode driver but till this is shorted out, please keep 16 bit.

8-bit color is good!

"For your amusement, I use 8-bit pseudo-color at work, although the machines that I run Puppy on don't (and obviously couldn't) run our pseudo-color application. On whether to drop 16-bit color support it would seem wise to to retain it as an option to allow users with older hardware to display Puppy's beautiful GUI.
