Monitor suggestions

<< < (5/6) > >>

Per E. Johannessen:
Now testing;

GPU: Radeon RX 7800 XT 16GB
(Same GPU I had a lot of trouble with when using an old Samsung monitor, SyncMaster SA950 27")
Monitor: Samsung Odyssey G8 G80SD 32" 4K OLED

Results;
HDMI: Offers same resolutions as the GeForce RTX 4060 Ti 16GB, max 1280x1024
DisplayPort: Offers lots of resolutions up to 3840x2160

Other issues;
When rebooting everything seems fine until the point where it normally displays the desktop, screen goes black with a blinking cursor in the upper left corner.
If I choose "Power off" the system shuts down as expected. When switching on again the system boots fine.

Just noticed another issue, don't know how/if it is related but it hasn't happened before.
After the cold reboot I wrote this message with Firefox and closed it when finished.
When trying to start Firefox again I get:
"Couldn't load xul.dll (OS/2 error 8, faulty module:
G:\programs\firefox\xul.dll"

Dave Yeo:
So things work fine after a cold boot but not a warm boot? Strange and perhaps you should open a ticket.
Firefox failing to start after a warm boot is also strange and something I've never heard of. Unluckily the error message isn't very informative on exactly what didn't load. Have you looked in popuplog.os2 for anything related? What is your VIRTUALADDRESSLIMIT in config.sys? Perhaps test with 2560. Did you ever run ffturbo install? If not, try running it.

Per E. Johannessen:
The system works fine after a cold boot except that Firefox can only be started one time only. Closing Firefox and then trying to start it again gives the "Couldn't load xul.dll". This is with VIRTUALADDRESSLIMT = 3072.
With VIRTUALADDRESSLIMIT=2560 it boots ok until it is about to start the desktop and then it goes black.

One thing came to my mind, earlier when trying the Radeon GPU with the old monitor something changed with the system. The shutdown dialog used to give me the possibility to choose which system I'd like to reboot to, I could choose any of the other OS installations on this system. At some point this has changed to the ordinary shutdown dialog with only the options "Power off" and "Reboot".

In order to change VIRTUALADDRESSLIMIT back to 3072 (from 2560) I cold booted another AOS 5.1 installation and edited config.sys for the troubled "G:\" installation which is AOS 5.0.6 and has all available updates installed.
From the AOS 5.1 installation, which has VIRTUALADDRESS=1536 and Firefox works fine, I was able to choose "Reboot to G:" and it actually worked fine.

So, obviously something has gone wrong on 5.0.6 on "G:\".

ivan:
Regarding your problem on 'G', have you run CHKDSK against that drive?

Now I've here two systems which behave very strange when trying to use VIRTUALADDRESSLIMT = 3072. I've not a single system/installation which works okay with this setting. I've the same intermediate 'out of memory' errors loading some programs. That's what in my config.sys about -

--- Code: ---REM 20210711 VIRTUALADDRESSLIMIT=2560 to 3072 because of qt browser
REM 20210711 neither simplebrowser nor Seamonkey nor ndpiso plugin works with 3072 -> 2900
REM 20211023 changed to 0xXX00 as Dave suggested in AN Testers from 2850 to 2816
VIRTUALADDRESSLIMIT=2816

--- End code ---

I've to add OpenOffice and VirtualBox also give such errors sometimes with 3072.
