Fedora 15 / Lenovo T420 / Sandy Bridge / SSD Crucial 256GB nearly 500 MB/Sec working perfectly with kernel 2.6.38, after upgrading to 2.6.40 (due to external monitor problem), speed decreased to 300 MB/Sec.
View 6 RepliesI'm in the process of switching back to Fedora after years of hiatus, but I can't get my wireless card working. The card itself is an Atheros AR2413, and the problem is that it seems to appear OK in various places, BUT it doesn't detect any networks. I'm on Fedora 14.

I am looking at various laptops at the moment and it's appealing to get a quad core (2720QM) when I need the power (yes, I have an application that can utilize many cores in parallel just fine). But, most of the time those extra cores will just there eating battery. Is it possible to switch a few off?

View 2 Replies View RelatedI have an i5 sandy bridge PC with a gigabyte H67M mobo. I have been running maverick amd64 till yesterday. On maverick graphic acceleration didn't work so I decided to upgrade. After upgrade my computer hangs during bootup (with ubuntu logo on screen). I cannot see messages on screen, wasn't ESC key for that? Live CD seems to boot but also hangs computer after loading purple login wallpaper before login dialog is shown. To me it seems a graphic card regression issue since intel mobo graphic card wasn't working fine on maverick too. Also tried to manage with fail-safe graphic mode but this also hangs computer. Is there any log where I can see errors during last bootup from maverick live-cd?
View 9 Replies View RelatedI built a new system with an Intel i5 and ASUS P8H-67-M LX motherboard that uses the Sandy Bridge chip set for video. It is a recent version without the original bugs. I use a 24" monitor, VisionQuest(Plain Tree Systems) and it supports 1920 * 1200. In System Settings > Monitor Preferences I confirm the resolution as 1920 * 1200. The Monitor is detected properly.
Drop down windows, such as my Firefox bookmarks drop below the bottom of the screen, without any scroll bars. I can drag the mouse pointer below the bottom edge of the screen. It disappears. In contrast, on my older system with Ubuntu 10.04 the mouse pointer will never totally disappear. The top tip remains.
It is like Ubuntu, when rendering the display, thinks I have something like a 1920 * 1280 screen, and everything in that bottom 80 vertical just falls off. Seems like a bug, and maybe a simple one to fix.
after installing Natty on my brand new shuttle with Intel's Sandy Bridge Core i5 (2500K), everything works fine except setting up a higher resolution fitting to my screen.All I need is a 2048x1152 resolution, but all the display configuration in the hardware section of the system settings offers is 1024x768, 800x600, 848x480 or 640x480.The monitor is connected via VGA since it doesn't have a DVI or HDMI plug.Is there a way to tell the system there is more capability? Do I need a different driver? What and where can I check this?
View 4 Replies View RelatedI had fedora 12 installed on a Macbook pro Intel first generation with ATI Radeon graphics card (see the attachment). Compiz crash when trying to watch *.wmv movie codified with wmvvc1dmo on kernel-PAE-2.6.32.9-67.fc12.i686. I want to convert the film to *.mpg, then I download the mplayer codecs in order to see the film, I can do it without problems with the on kernel-PAE-2.6.31.12-174.2.22.fc12.i686. But I updated my system last Saturday and when I was trying to see the movie again the computer began to respond really slow, then I began to close applications and when I tried to restart I got the message: "compiz is not responding".
I tried again but the same problem. Other thing that I noticed is that when the computer go to sleep, when I wake up it, the display show horizontal black spikes, it is like it doesn't have the appropriate refreshing rate. I think that the problem is related with the acceleration on graphic card. Yesterday, I booted on kernel-PAE-2.6.31.12-174.2.22.fc12.i686, and I watched the film, and the wake up was without problems. That is the reason I call it a regression.

I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.
View 3 Replies View RelatedSearching around, I couldn't find anyone talking about this so I wonder if it's something specific to my BIOS and/or chipset, an NVIDIA N67 aka C67 aka GeForce 7000M / nForce 610M IGP on an Acer 5520 laptop. 13.1 has always worked fine, though I needed NVIDIA's binary blob to get full performance from my video. Unfortunately a weird problem has cropped up with 13.37. I didn't notice it at first (when I wrote about my Nouveau woes), but noticed it tonight:
Only while running X, regardless of kernel (2.6.37.6 or 2.6.38.4) or video driver (Nouveau or the proprietary blob), with the laptop plugged in, if I pull the plug the usual ACPI event is generated; however, the IDE/SCSI/SATA subsystem also proceeds to do a reset on the drive, which disconnects it. Following this, the entire computer crashes. Since X is running, I haven't been able to see the console for any panic messages: it just freezes. If I have an xterm open as root, I can still try running commands, but nothing happens, probably because it can't load it from disk, but as soon as I exit back to my normal user, it locks up too and I get nothing. The only way out is to do the ol' holding the power button for 4 seconds thing to force the machine off.
My next idea, when I have time, is to try compiling the latest 2.6.39 kernel with the defaults that Pat gave out; if that fails, then I'll start removing things until it starts working. But it would sure save a lot of time if any of you had ideas or, better, solved this already.
I've a strange regression with Slackware 13.37 and Emacs. In Slackware 13.1 (and all previous versions since I started with Slackware 11), Emacs in X-windows looks good regardless of the window manager. I've attached a show of Emacs in Slackware 13.1 to show what I mean. Notice the nice logo and fonts. In Slackware 13.37, the logo is missing and the fonts are different in KDE (and Window Maker). The logo is back and the fonts look good in XFCE (and TWM). See the other attachments.

View 2 Replies View RelatedI have 2 NIC's in a box. One of them is external and doesn't matter for this question I don't think.
The other NIC is 192.168.100.3. It hosts an iSCSI Target and SMB Share on my LAN. It's works great.
I have another PC that has NIC at 192.168.100.101 and it hosts my DHCP (Scope: 192.168.100.5-25) server for my LAN.
I have a hardware firewall at 192.168.100.1 and it serves inet to the LAN on a different external connection.
So...
I currently have a WAP (cheap p.o.s. netgear router in WAP mode that keeps overheating). I want to eliminate the WAP device and add a WiFi NIC to the Top PC above.
So, on the first system I would have:
NIC 1: External IP and External Gateway
NIC 2: Static IP 192.168.100.3
Proposed WiFi NIC 3: Static 192.168.100.4
Question:
If I bridge NIC 2 and NIC 3 like this:
# brctl addbr br0
# brctl addif br0 eth0
# brctl addif br0 eth1
Then I simply put the WiFi in Ad Hoc, will another WiFi in Ad Hoc (for example my laptop) be able to "see" 192.168.100.101 (DHCP) & 192.168.100.1 (Gateway) (via WiFI 192.168.100.4 through the bridge to 192.168.100.3 and on to the LAN)?
Also, can the two NIC's be bridge together even though they are the SAME subnet?
I tried google but without success. I have a small home network and one computer has to work as a bridge (comp1), it connects to the internet through wlan and is connected with cable to other computer (comp2), I would like to to make that second computer member of a local network with internet access.I was trying this:

ifconfig wlan0 0.0.0.0
ifconfig eth0 0.0.0.0
brctl addbr br0
brctl addif br0 wlan0

View 3 Replies View RelatedI'm trying to set up a Linux box with three ethernet interfaces as a bridge where I can do some packet filtering. I don't want this box to have any IP stack, packets that are allowed through the filter should be forwarded without changes just the way a switch would do it. I have build a kernel with ethernet support but no IP stack. It detects my interfaces, and I can bring them up with the ifconfig or ip commands. But when I try to start a bridge with brctl I get this error message:
can't setup bridge control: Address family not supported by protocol
A google search for that error message gave me no results at all. The command I used was "brctl addbr br", which does work on a full installation. Does brctl require IP support in the kernel? That would be a bit odd I think, since brctl doesn't do anything IP related, everything it does is at lower layers?
Does anybody know what the above message means, and what I might have been doing wrong?
What I am trying to do: bridge 2 NICs in my linux box eth0 connects to linsys router (which in turn connects to internet) eth1 connects to Xbox 360
What I did:
Code:
ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0
brctl addbr br0
brctl addif eth0
brctl addif eth1
[Code]...
I'm sure this is a bridging issue and there is just some option I'm not setting correctly. Also, the reason I'm connecting the Xbox 360 directly to the linux box and not to the router is for traffic monitoring purposes. Note that all connections and functionality work perfectly when the Xbox IS connected through the router.
I'd like to pass all traffic between bridge ports via the FORWARDING chain, so I changed following sysctl parameters:
Code:
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1

View 2 Replies View RelatedMy current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).
So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.
