[Bug 154647] Possible severe conflict between intel X server and Broadcom wifi
Public bug reported: This is my post from the forums (I have reported this as a bug now because I believe I have found a partial solution): http://ubuntuforums.org/showthread.php?t=579941 Subj: Networking (wifi) latent/unusable in X but fine in a vc? I have a rather strange problem. I have a Compaq C550 laptop (C552US) with integrated WiFi. I have upgraded from Feisty to Gutsy. I am using ndiswrapper. The computer boots up, the WiFi card associates with my AP and receives an address. Any network access is unusably slow. Pinging either of my APs, I can see that most packets are dropped and those that are returned have a very long rtt (mostly 1-2sec+). However, here's the kicker: if I switch to a vc (using Ctrl+Alt+F#; not logging out or killing X), network access is slick as it should be, with no or minimal dropped packets. [EDIT: Incoming traffic is fine as well; e.g., if I ping this machine from another the latency is normal). A bit of a longshot, but I thought perhaps somehow the video card was assigned overlapping resources (io, irq, etc) with the WiFi card - it is not. Please note I am still using the 2.6.20-15 kernel from Feisty. I wanted to use the 2.6.22-14 as shipped with Gutsy so I could try the in-kernel bcm43xx driver, but unfortunately that has an even nastier still problem: the machine locks up hard at a somewhat random time after the gdm login screen [edit: using either the i810 or intel X server] (usually after logging in). The WiFi is an internal miniPCI Broadcom 4311 (according to lspci, rev 01) Video is i945GM. I have also tried removing as many unnecessary kernel modules as possible and tried with and without the 915resolution util. Cheers, Jesse EDIT: I got this working. I can confirm this appears to be a conflict of sorts with the "intel" X server; I thought for sure I had tried this but apparently not: using the legacy i810 server instead solves this problem for me. There doesn't appear to be any remotely pertinent information in any system logs, X startup log, etc. drm module version is 1.1.0 20060810 i915 module version is 1.6.0 20060119 ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- Possible severe conflict between intel X server and Broadcom wifi https://bugs.launchpad.net/bugs/154647 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
