Switch to Widescreen display, and Orac loses a brain.

Well, thought it was going to be another quick project....ended up taking the whole afternoon and then some.

I had gotten some speaker options using Amazon Prime, so that I could swap out the old 17" LCD monitor with built-in speakers for the Vison 21.6" MW22E-BAD monitor that had been bumped from Zen recently.

I decided I wanted something <$25 and USB powered, and I bought two choices...figuring that the other would go on Orac, since I've been wanting sound on there too for a while. I went a Coby Portable MP3 Speaker System CSMP48, Black and an Altec Lansing iML237USB ORBIT Ultra Portable USB-Powered Speaker.

I decided that I got with connecting the Coby to Gumby and putting it below the monitor...turned out it was the only one for the situation. The Coby has a 3.5mm jack to connect to the output and a mini USB jack with cable to power it. While the Altec only has the USB cord...it isn't just powered by USB, but it does its own sound. While that would work on either computer, it wasn't really what I had in mind for Gumby....or Orac. So, the Coby went in place and then I went to work on swapping the Vison 21.6" monitor into place.

Things looked weird on all computers, since I had to tell each computer about the change in display.

Gumby, Windows XP was a problem...in that it wouldn't let me set 1680x1050 at first. Eventually, I uninstalled the driver, rebooted and now it shows tons of modes that I'm not interested in. I set it to 1680x1050 and 60Hz and triggered an autoconf and done. I didn't decide on 60Hz right away, but that's where I settled. The other choices were 70Hz and 75Hz.

Then, BOX....I used the Monitor app to change things and it saw that the monitor was different and settled on 1680x1050 and 70Hz (again not first choice, but where I settled). Why...when they were all 75Hz...the had slightly different ideas on where the image was centered, so I went with 3 different verticals so the monitor would have the desktop properly positioned for all 3. Wonder what I'll do when I get LHAVEN going? &#58;&#104;&#109;&#109;&#58;

Then ORAC, which was harder....the Monitor app wouldn't see that resolution, and reconfigure has apparently gone away. Eventually, I discovered xrandr and cvt and got it working. As 1680x1050 and 75Hz.

Mostly.....

Morning Orac outage

Well, Orac was being somewhat unresponsive this morning.... Looks like early this morning the system stopped answering to Cacti, with the temperature of the GPU rising to a new high. Don't know what the high would've been, because there was no snmp data for a while. GPU temp did recover, but the display did not.

Ended up rebooting, needed the excuse to see external journal work....

Once backup, I switched back to internal journal...but one of maximum size rather than default size. And, then shutdown the system to extract the PCI Compact Flash card. During the reboot to see external journal work...I realized that I wasn't likely to see much performance gain from getting faster compact flash since the card itself was only UDMA/66. So the 133x CF is already faster than the card?

Probably should've fsck'd manually after the switch back....some discussion thread suggested doing this after fiddling with journal settings. But, its fsck'ng now after the boot back up. Apparently superblock had invalid external journal superblock hint? And, auto fsck failed, requiring manual fsck.

Downside of internal journal is that it can only be a max of 400MB (an improvement from the 128MB default I had before)...but that's only like 0.01% of my total space. And, there was a discussion thread that seemed to suggest a journal size of 0.2% would yield better improvement....I didn't do the whole 16GB CF card...though wonder how much that would've helped.... But 0.2% would call for a journal of ~10.9GB. Suppose I could turn off data journaling, especially since there are files that backuppc puts down that are bigger than the 400MB journal. Though I think the ordered/writeback modes usually just do metadata journaling, while I had switched it to data journaling when I was playing with external journals...but I didn't switch it back.

Wonder which of writeback or ordered would be more optimal for this FS? &#58;&#63;&#63;&#58;

The Gumby Torture has ended

That is Gumby was torturing me!

It all started around May 13, 2010....and could ended around...sometime back in April, 2011...but had to let it drag on to today...July 23, 2011.

Gumby had been torturing me more and more lately....largely because when I upgraded it in May 13, 2010...it became my second fastest system at home, and my fastest Windows XP box. Ole TARDIS was only a Pentium 4 3.2GHz w/HT. While new Gumby is a Pentium D 3.4GHz.

Though while TARDIS was still my main Windows XP system, I largely kept Gumby's role the same...though it did pick up a few things the ole Gumby didn't do, due to it having more juice and being less cluttered in its registry and driver hell. Like a new DVD burner, or running a few more CPU and/or memory intensive apps (things that didn't work to well on P3-933MHz and/or only a max of 512MB...)

But, the problem with new Gumby was that its a legacy free box. No PS/2 mouse or keyboard ports (though it's strange that I can still buy new systems that have one or two PS/2 ports, something about the reliability of PS/2 mouse and/or keyboard over USB probably... this KVM switch was kind of holding up whether or not I would be requiring PS/2 ports on whatever mobo I decide to build the new LHAVEN around.)

I had gotten USB PS/2 adapters to keep using my old keyboard/mouse and KVM setup on Gumby (though the keyboard and mouse have upgraded a few times since the Trendnet TK-408) Also, I think the mouse has always been a USB kind with a PS/2 adapter. Originally a ball type, now an optical type....some day I'll get some laser mice here and there...

Problem was that the USB PS/2 adapter was less than reliable or usable. I was still using the Kingwin one that I got to start with new Gumby. Which worked the best, except that every now and the the mouse would stop responding. I could have to stop using the mouse for a while, and it had to be absolutely still during the stop....and then something would reset and it would work again. I had tried a TrendNet, thinking it would go with the KVM....but switching away and then back on the KVM would cause the scrollwheel functionality to go away, and that required me to unplug/replug the USB adapter to get scrollwheel working again.

I also tried a PCI PS/2 card, but found that internally was just another USB PS/2 adapter...just in a slot consuming form, plus it didn't get along with the other PCI card (firewire, and I use firewire external storage on Gumby)...also it exhibited the same problem that the TrendNet USB PS/2 adapter did, except that its a little harder to unplug the card to reset it at will...

So, I stayed with the KingWin and set my sight on a KVM.

the 'gumby' upgrade, not so good.

actually, pretty bad....

So, while I was looking at the items for the 'lhaven' upgrade...I happened to type other things I might want, and came across a PCI PS/2 adapter.

The new 'gumby' is legacy free...which was causing problems working under my KVM setup. Not quite ready to upgrade the KVM to one that does both PS/2 and USB....so I've been using USB to PS/2 adapters. So far I've tried two. Kingwin and Trendnet. The KVM is a Trendnet, so I kind of hoped the Trendnet one would work.

The Kingwin was first....it works pretty good, except that once in a while the mouse to stops moving. I have to let the mouse sit idle for a moment and then I can move it again. If I don't let go of it, the mouse still being active prevents the 'reset'. Annoying....

So, I got the Trendnet adapter....well, things work...pretty much all the time...except the scrollwheel. And, I've gotten quite fond of using it. Whenever it stops working, I have to unplug the adapter and plug it back in. This is inconvenient and even more annoying....

So, I switched back to the Kingwin, until I decide on what I would use. I wondered if there were a more hardware solution...IE: PCI PS/2.

So, I snapped one up on eBay to try out.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
