Fedora 22 Networking
by Howard Gibson 09 Aug '15

09 Aug '15

I have just installed Fedora_22 on my Lenovo Thinkpad T400 laptop. I cannot get the networking to work, Ethernet or Wi-Fi. I can turn Wi-Fi on, and I can see the Wi-Fi servers. When I connect to mine, it just sits there trying to connect until it times out. I tried connecting with an invalid Wi-Fi password, and it prompted me for the correct one, so it is validating this, but not connecting. When I look at dmesg, I see a bunch of messages about authenticating and deauthinticating to a MAC address. This MAC address matches the address of my router except for the last number, which is 87, and should be 86. Fedora_22 no longer has /var/log/messages. I had some difficulties when I did the install from DVD. A screen came up and said "Oh no! Something has occurred and the system can't recover. All extensions have been disabled as a precaution." I searched the web and I removed xorg-x11-drv-libinput. This got the install working. I removed it from the actual installed computer, as per the instructions on the website. I was having network problems both before and after I did this. Has anybody seen anything like this? Fedora_20 was a fairly easy install for ordinary mortals. Fedora_22 seems to be a huge step backwards. Thanks. -- Howard Gibson hgibson(a)eol.ca howard.gibson(a)teledyneoptech.com jhowardgibson(a)gmail.com http://home.eol.ca/~hgibson

Once you find the UEFI settings in the BIOS you may find that access to it is disabled. You will most likely need to set a supervisor password for the BIOS before it will let you have access to the UEFI settings. Just remember to remove the supervisor password when you are done (if you don't want/need it). -- Cheers!

Unfortunately, there is no standardized way of disabling the UEFI and switching back to using BIOS. In general, there are basically two challenges: 1) getting the attention of the firmware that runs on initial startup before the operating system (Windows or Linux) gets to start, and 2) navigating the setup menus to disable the UEFI. Doing the first usually requires you to press or hold down a particular key at a particular time, which one and when depends upon the manufacturer. Depending upon a number of factors, you may or may not see a splash screen providing a hint while booting. Knowing the make and model of your computer can also help to determine this. Most computer manufacturers should have user documentation in PDF format that you can download from their web site. I hope that this helps. --- Talk Mailing List talk(a)gtalug.org http://gtalug.org/mailman/listinfo/talk

Re: [GTALUG] Thinkpad T420 as a VM host

How is the state of the kvm over lan, Serial over Lan, and drive over lan implementation on the T420 wrt Linux? Can the keyboard, drive, etc be securely accessed from behind a firewall? ‎ ‎ Original Message From: D. Hugh Redelmeier Sent: Wednesday, August 5, 2015 23:20 To: GTALUG Talk Reply To: D. Hugh Redelmeier Subject: Re: [GTALUG] Thinkpad T420 as a VM host | From: William Park <opengeometry(a)yahoo.ca> | If T420 can do 16GB, then I can replace my desktop with it, which has | 16GB (DDR3-1333) right now. But, I have question about T420 keyboard. Most notebooks don't have the performance of desktops because the tradeoffs are different. - Most notebook CPUs are weaker than desktop CPUs. Fewer cores and lower clock rates, for a start. There are exceptions but they are outliers. - Ditto for GPUs. But GPUs may not matter much for what you hope to do. - adding disks and RAM is more constrained. May well be OK anyway - desktop displays can and should be better than notebook displays (but I seem to care more than most folks) - in a fixed installation, notebooks are a bit awkward (but you can fix that by using an external monitor, keyboard, and mouse). Many new notebooks don't let you replace batteries, RAM, or disks. Beware. Of course this is not the case with ThinkPad T420 notebooks. If you want portability, the T420 is too old: more modern Intel CPUs take a lot less power for the same performance and thus the battery lasts longer. If you don't want portability, a W-series ThinkPad may be more powerful and expandable (may depend on the generation). My son's W520 will accept up to 32G of RAM, I think. Lennart has a similar one. And it comes with a larger screen. Here's an example of a very powerful non-portable notebook: <http://www.nmicrovip.ca/rog-core-i7-4710hq-16gb-ram-1tb-hdd-17-3-gtx860m-2g…> - quad core i7-4710hq - 1920x1080 17" IPS screen - 16G of RAM (that may well be the limit) - NVIDIA® GeForce® GTX860M Graphics with 2GB GDDR5 VRAM Beware: bilingual keyboard | I currently have T43, and its keyboard is difficult to type on, at least | for me. Many people love ThinkPad keyboards, especially the ones on older ThinkPads. One of the main complaints about newer ThinkPad keyboards is "they aren't as good as the old ones". How can this square with your observations? - keyboards are at least partially a matter of personal taste - your T43 might have a dud keyboard. In any case, the only way you'll really know if you'll like a keyboard is to try it. Me? Lots of keyboards seem bad, some seem elegant but not to my taste, many seem fine / good enough. None has captured me. | - it's stiff, so you need to "push" rather than "tap", | - it doesn't spring back, fast enough or "crispy" enough, so you | actually notice and become aware of the keypresses. And, that | interferes with my typing. Many typists like being sure when they press a key. Significant key travel is considered desirable by many (but not all). And rare in modern notebooks because of the quest for thin. A tactile signal of a keypress registering is considered a Good Thing (except by many gamers). Something sort of lost with most modern key structures. There has been a renaissance of mechanical keyboards. They cost several times as much as regular keyboards. And a great deal has been written about the characteristics of each. I thought that I'd like Cherry blue, brown, or clear keys. <http://www.keyboardco.com/blog/index.php/2012/12/an-introduction-to-cherry-…> I'm using a mechanical keyboard to type this (Rosewill RK-6000; imitation Alps keys, somewhat like Cherry Blue). It is fine, but not a revelation. I have the same reaction to my wife's keyboard with Cherry brown switches. I find it especially disappointing that a key can register on my keyboard without a click and a click can happen without a registration (these problems don't seem to happen with the way I type).

gimp.org no longer in existence?

Hi I was trying to reach gimp.org, and it appears that its domain is parked. I have tried different browsers, VPN, and so on, and I get to the same site hosted by Domain Name Sales. Meanwhile, Google still points to parts of GIMP as though it still exists. Not sure what is going on. Have they been hacked? Paul

<snip the problem description> > > Can you duplicate the problem, all the while keeping a log of the > various temperatures that are available to you? The CPU can monitor a > few of the system temperatures, but I don't remember how (google > surely does). I was thinking of picking up one of those lazer doohickey's the health department uses to measure the temperature of steam table contents. I can't see if I was touching the cpu die or the bottom of the heat-sinc. For now I'v installed lm-sensor which shows: [root@solon ~] # sensors atk0110-acpi-0 Adapter: ACPI interface Vcore Voltage: +1.12 V (min = +0.85 V, max = +1.60 V) +3.3 Voltage: +3.26 V (min = +2.97 V, max = +3.63 V) +5 Voltage: +5.12 V (min = +4.50 V, max = +5.50 V) +12 Voltage: +11.98 V (min = +10.20 V, max = +13.80 V) CPU FAN Speed: 2755 RPM (min = 600 RPM, max = 7200 RPM) CHASSIS FAN Speed: 0 RPM (min = 600 RPM, max = 7200 RPM) POWER FAN Speed: 2428 RPM (min = 600 RPM, max = 7200 RPM) CPU Temperature: +43.0°C (high = +60.0°C, crit = +95.0°C) MB Temperature: +40.0°C (high = +45.0°C, crit = +95.0°C) k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +36.0°C Core0 Temp: +43.0°C Core1 Temp: +40.0°C Core1 Temp: +38.0°C So far It looks like I don't have the chassis fan plugged into the right slot. But at least the unit works without blocking output of the air conditioner any more. > > Can you affect uptimes by running CPU-bashing programs? > > Are crashes at predictable uptimes when you are running identical > workloads? Are these times affected by your ad hoc cooling boosters? As you can see from lm-sensor, after the firmware update, I'm within operating parameters now. One feature of this motherboard is the ability to recover from different bios's.

Apparently ASUS has a MS utility they ship with the board. Ai gear 2, which allows overclocking the MB from userspace. The condition seems similar to the laptop I experienced where the MS OS had hooks into controlling the power management. > > "auto" is not described but it should meen "no overclocking". > Especially if all the related settings are "auto" too. > > When you flash new firmware, you are supposed to select "load setup > defaults" in the CMOS setup "exit" tab.

That's what I chose, I had assumed conservative settings but perhaps that ASUS overclocking utility only works under one condition, auto. I'll never know, I don't use Windows.

The little graphic thingy in System Monitor which gives a visual output of load as a line graph for each CPU die, as well as for Memory/Swap and Network. At this time and at increased resolution the load line hovers around 60% as opposed to the old firmware at 800X600 which showed 85-100% load with video on VLC. > > | I do note that desktop > | sprite animations are slower. > > What are "desktop sprite animations"? The mouse pointer? Sprites are a term for layers used in animations. So in the case of the mouse pointer, it exists on a sprite layer. Any windows animations like dragging the widget around aren't dragging a box per-se, they are moving the indicator (0,0) to the point where the new sprite is created, leaving the old one to be destroyed on the screen redraw.

I like using Linux because I always feel I've learned something. Not how to do some thing. At this point I'm still a little at odds with what to do about QT, but I can live with this state of things. It looks to me like this bios is heavily vested in Windows gamer land with the bios optimized to accept hooks from the ASUS GUI overclocking utility. This board looks like it has good audio support so it would be nice to have an all in one home theatre with surround sound as my workspace, but it's not really a necessity. Anything else I do to this unit is more out of curiosity than needs. Thanks for the pointers. Now my SO won't have to wonder where all her nail polish remover went.
