Description Mike FABIAN 2013-10-29 12:52:24 UTC

I installed Fedora 20 Beta TC6 in qemu:

ionice -c 3 qemu-kvm -enable-kvm -global qxl.ram_size=1x1024 -m 2048M -smp 4 -drive file=./Fedora-20-Beta-TC6-x86_64-netinst.iso.qcow2,index=0,media=disk,cache=unsafe -localtime -serial file:/tmp/qemu-Fedora-20-Beta-TC6-x86_64-netinst.iso.qcow2-output.log -name Fedora-20-Beta-TC6-x86_64-netinst.iso.qcow2 -cdrom /local/mfabian/iso/Fedora-20-Beta-TC6/Fedora-20-Beta-TC6-x86_64-netinst.iso -boot c -spice port=6000,disable-ticketing -vga qxl -display vnc=:4 -net nic -net user,hostname=Fedora-20-Beta-TC6-x86_64-netinst.iso.qcow2,hostfwd=tcp::5556-:22 -monitor stdio -usb

- Japanese default installation (should not matter, I think)
- After the installation finished and logging into Gnome
  I installed KDE as well with
  “sudo yum groupinstall kde-desktop-environment”
- Log out of gnome
- Log into KDE
- There is an ibus icon visible in the panel
- Clicking it with the left mouse shows input methods,
  ibus-kkc (日本語 - Kana Kanji) and ibus-anthy (日本語 - Anthy)
  and a keyboard layout (英語 - English (US)

  (Side note: Why Anthy is there I don’t know. I didn’t add it,
  it was already there. The ibus-anthy package is installed, I
  installed that manually before when testing on Gnome).

- Click with the right mouse button on the ibus icon pops up
  the menu:

  設定 (P)                     <- this means "Setup"
  このアプリケーションについて(A)
  -------------------------
  再起動
  終了(Q)

- Click on 設定 (Setup)
- The desktop may freeze already now
- If the desktop does not yet freeze, the setup tool window of ibus
  opens.
- Most likely the desktop will freeze now.
- If it still does not freeze, click the
  インプットメソッド (= Input Method) tab
- Check the checkbox in front of
  アクティブなインプットメソッドをカタマイズする(M)
  (= Customize active input method)
- Open combobox
  インプットメソッドの選択
  (*Very* rare to get that far, usually it freezes much earlier)
- The item at the bottom of that combobox is
  すべてのインプットメソッドを表示する (= “Show all input methods”)
  Click that.
- If you are very lucky and it still doesn’t freeze,
  click the combobox again and try to add some additional
  input method.


Result:

Usually the desktop freezes very early in that procedure.
With “freezes” I mean that I can only see the mouse cursor moving,
but that’s it, it is not possible to do anything else anymore
(close windows, move windows, focus windows, type, nothing works).

Freezing the desktop is also possible like this:

- Click with the left mouse button on the ibus icon and select
  ibus-kkc (日本語 - Kana Kanji)
- (optionally type some Japanese somewhere, this actually works ...)
- Click the ibus icon again with the left mouse and select
  設定 (= Setup), the setup tool of ibus-kkc.
- Setup tool opens, desktop always freezed immediately for me,
  I could not get any further in the setup tool.

I could reproduce the same problem with Fedora-Live-KDE-x86_64-20-Beta-TC6.iso
in qemu:

ionice -c 3 qemu-kvm -enable-kvm -global qxl.ram_size=1x1024 -m 2048M -smp 4 -drive file=./Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2,index=0,media=disk,cache=unsafe -localtime -serial file:/tmp/qemu-Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2-output.log -name Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2 -cdrom /local/mfabian/iso/Fedora-20-Beta-TC6/Fedora-Live-KDE-x86_64-20-Beta-TC6.iso -boot c -spice port=6001,disable-ticketing -vga qxl -display vnc=:5 -net nic -net user,hostname=Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2,hostfwd=tcp::5557-:22 -monitor stdio -usb

After the desktop started, I installed ibus-kkc with

    “sudo yum install ibus-kkc”

Then restarted ibus with

    “ibus restart”

Then tried to open the  setup tool of ibus to add ibus-kkc
to the list of input methods

-> desktop freezes.

Could I give more information to help here? Log files? Which ones?

Comment 4 Mike FABIAN 2013-10-30 14:51:59 UTC

I tried the same on a Lenovo T500 which I upgraded using fedup from f19
to f20, I could *not* reproduce the problem there.

Comment 5 Mike FABIAN 2013-11-01 11:33:38 UTC

Also happens when I use “-smp 1”:

ionice -c 3 qemu-kvm -enable-kvm -global qxl.ram_size=1x1024 -m 2048M -smp 1 -drive file=./Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2,index=0,media=disk,cache=unsafe -localtime -serial file:/tmp/qemu-Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2-output.log -name Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2 -cdrom /local/mfabian/iso/Fedora-20-Beta-TC6/Fedora-Live-KDE-x86_64-20-Beta-TC6.iso -boot c -spice port=6001,disable-ticketing -vga qxl -display vnc=:5 -net nic -net user,hostname=Fedora-Live-KDE-x86_64-20-Beta-TC6.iso.qcow2,hostfwd=tcp::5557-:22 -monitor stdio -usb

Comment 6 Mike FABIAN 2015-04-21 07:25:38 UTC

This does not happen with Fedora-Live-Workstation-x86_64-22_Beta-3.iso
anymore.
