RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jason 2010-05-28 17:41:15 UTC 
Description of problem:
When I either use "xm console" or telnet to a physical serial port and I view the console through a window in GNU screen, the display is mangled and unusable.  If I exit screen and view xm console or telnet, it works fine.

At the beginning of the install, I only see:
"
Welcome to Red Hat Enterprise Linux 6 for x86_64

                    ������ Choose a Language �����
"

Version-Release number of selected component (if applicable):
screen-4.0.3-1.el5_4.1.x86_64
RHEL 5.5 Dom0 when installing RHEL 6.0 Beta 1 DomU

How reproducible:
Every time.

Steps to Reproduce:
1. On RHEL 5.5 Dom0, 
# screen #(no custom .screenrc)
# virt-install -n rhel6test2 -r 1024 --vcpus=1 -f /export/vms/rhel6test2.dsk -s 10 --nonsparse  -l http://admina03/Packages/media/rhel-x86_64-es-6_up0/ --network=bridge:xenbr310


Alternatively:
1. Insert RHEL6 CD on physical system.
2. Connect to the serial console "telnet terminal-server 5024"
  
Actual results:
"
Welcome to Red Hat Enterprise Linux 6 for x86_64

                    ������ Choose a Language �����
"

Expected results:
Full display of text-based user interface.  (Note: the lines outlining the window and OK button display correctly outside of screen, but they don't paste in this text box).

Comment 2 Chris Lumens 2010-05-28 17:48:23 UTC 
Have you tried messing with the terminal type in screen?
Comment 3 Jason 2010-05-28 18:08:25 UTC 
Hi Chris,

Outside screen:
  TERM=xterm   works
  TERM=screen  works

Inside screen:
  TERM=screen  does not work
  TERM=xterm   does not work
Comment 4 Chris Lumens 2010-06-02 17:11:19 UTC 
What about TERM=linux?  That's what anaconda's init sets up and expects.
Comment 5 Jason 2010-06-02 18:27:58 UTC 
I tried exporting the TERM as both linux and then vt100 with no different results.  I'll add that I'm using xterm in cygwin.  I tried the same test with Putty, and I get the same results.  It works outside of screen, but not inside of screen.  I imagine some default setting in screen is not passing the graphics characters correctly.
