OK, The setup, I'm currently working on, has 3 monitors, 2 that are turned 90 degrees anti-clockwise and 1 monitor in normal rotation. The 2 that are turned on their ends, the one connected to a mini display port, displays correctly, the middle monitor, displays upside down, though the mouse moves correctly. Anything I drag to the middle monitor displays 90 degrees turned clockwise. This monitor is on HDMI.
The graphics card is an OLD Fire GL card running the 2 turned monitors and the 3rd monitor is running off the motherboard. The system as a whole, i7 4790, 32gb ram, is running slower than the virtual machine I tested it on in my Windows on this same hardware.
It seems to me this is a driver issue and NOT Garuda nor Arch.
Where should I go to begin to find answers to these issues?
I dual boot this system with Windows 10 on separate SSD.
I'm very impressed that Garuda installed the dmraid or MDADM and sees the fake Raid I have on this system in NTFS..
Otherwise I believe Garuda to be the absolute best GNU/Linux distro! I have tried them all!, well most of them anyway..
Goto the gear icon in your dock, then display and monitor. you can change the orientation there to whatever you please..also check you REFRESH RATE. this is the only thing that i ever encounter issues like this. sometimes my 1080p 40 inch Samsung tv detects as 24 Hz, then is switch to 60 Hz and everything is all better.
mods..do you have issue with me trying to help others that do not comply with the inxi -faz rule ? if so ill desist. i dont mean to break your forum rules if you view this as such, im just trying to help others enjoy garuda as much as i am...and i know the learning curve is steep for some so i do what i can. many of these people may not even understand what the inxi -faz rule is about or what it does.
windows people arent command line proficient since windows 9x era. and even then dos is not linux. anyways like i said, let me know if you would like me to ignore those who dont comply with the inxi -faz rule.
I edited your post with inxi block formatting to improve readability. Hope you don't mind...
I'm not an expert of multi monitor setup.
Maybe you could give a look here, but I don't think you'll find your answer there. If I understand correctly your issue is about performance, the graphical setup works, right?
I know I too often point to the BIOS, which might not be the root cause, but yours seems very old...
Have you tried a simple set-up with one monitor or maybe two, to see if it performs better?
You could also maybe check if the situation improves temporarily disabling the compositor (alt+shift+f12).
Finally, you could maybe give a look at the running processes, to see if there's anything acting a bottleneck (sometimes baloo can be guilty there).
No idea about your FirePro... I just see almost all the search results on the web pointing to radeon (ATI), without much details or hints...
I hope someone else can help better....
