For me the solution was to blacklist the radeon module. In /etc/modprobe.d/my-blacklist.conf (can be any file in this directory, but I prefere my own) I added the two lines: # blacklisting radeon driver as it will not allow 2.6.38-8-generic to boot blacklist radeon
from before I also have this lines #blacklist closed source fglrx driver for graphics card blacklist fglrx lsmod output now looks like this: me@my-laptop:/etc/modprobe.d$ lsmod Module Size Used by parport_pc 36959 0 ppdev 17113 0 binfmt_misc 17565 1 snd_hda_codec_hdmi 28103 1 joydev 17606 0 snd_hda_codec_realtek 336693 1 arc4 12529 2 snd_hda_intel 33211 2 snd_hda_codec 103804 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_hwdep 13604 1 snd_hda_codec snd_seq_midi 13324 0 ath9k 118238 0 snd_rawmidi 30486 1 snd_seq_midi snd_pcm 96625 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_seq_midi_event 14899 1 snd_seq_midi i915 514985 8 mac80211 294370 1 ath9k snd_seq 61621 2 snd_seq_midi,snd_seq_midi_event snd_timer 29602 2 snd_pcm,snd_seq snd_seq_device 14462 3 snd_seq_midi,snd_rawmidi,snd_seq drm_kms_helper 42136 1 i915 uvcvideo 72195 0 acer_wmi 23771 0 ath9k_common 13851 1 ath9k ath9k_hw 323077 2 ath9k,ath9k_common snd 67382 14 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_rawmidi,snd_pcm,snd_seq,snd_timer,snd_seq_device ath 23773 2 ath9k,ath9k_hw sparse_keymap 13898 1 acer_wmi drm 227495 4 i915,drm_kms_helper cfg80211 178528 3 ath9k,mac80211,ath videodev 82052 1 uvcvideo psmouse 73535 0 intel_ips 18097 0 v4l2_compat_ioctl32 17078 1 videodev i2c_algo_bit 13400 1 i915 video 19438 1 i915 serio_raw 13166 0 soundcore 12680 1 snd snd_page_alloc 18529 2 snd_hda_intel,snd_pcm lp 17825 0 parport 46458 3 parport_pc,ppdev,lp usbhid 46956 0 hid 91020 1 usbhid firewire_ohci 40370 0 ahci 25951 2 firewire_core 62646 1 firewire_ohci libahci 26642 1 ahci sdhci_pci 13989 0 sdhci 27387 1 sdhci_pci crc_itu_t 12707 1 firewire_core atl1c 41171 0 but I will still hope the Ubuntu crew will fix the problem as I want the same possibilities as with the 2.6.35-28-generic kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775462 Title: [Arrandale] Xorg freeze (hybrid graphics) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
