https://bugzilla.novell.com/show_bug.cgi?id=874072 https://bugzilla.novell.com/show_bug.cgi?id=874072#c0 Summary: Font "Droid Sans Mono, Regular" does not display underscores Classification: openSUSE Product: openSUSE 13.1 Version: Final Platform: x86-64 OS/Version: openSUSE 13.1 Status: NEW Severity: Minor Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: martien.friedeman@gmail.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- Created an attachment (id=586738) --> (http://bugzilla.novell.com/attachment.cgi?id=586738) Droid Sans Mono drops the underscore in small fonts User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:28.0) Gecko/20100101 Firefox/28.0 Droid Sans Mono, Regular does not display the underscore when the font-size is 10px or less. On font-sizes 11px and over, it is displaying them as expected. You can easily see this under 'Font Management' in 'Configure Desktop'. Reproducible: Always Steps to Reproduce: 1. Click 'Configure Desktop' 2. Select 'Font Management' 3. Select font 'Droid Sans Mono' 4. Right-click in the preview pane. 5. Select 'Change Preview Text...' 6. Change 'The quick brown fox jumps over the lazy dog' to '__bob__' 7. Look at the top line where the font is smallest. 8. Notice the underscore character is not showing. Actual Results: The underscore character does not show when a small font-size is used. Expected Results: The underscore character should always show. Even when a small font-size is used. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

- Change AntiAlias : No effect - Change forceDPI : No effect
The change I expected to be most likely to have an effect is the sub-pixel type. Did you try changing that, and restarting KDE afterward?
- Change .xinitrc, remove the line 'xrandr --dpi 90.6 : Yes, the underscores now do show. And they still show when I re-add that line. Go figure!
Most people sensitive to fonts find a DPI that is a multiple of 4 (or better 12, or still better 24) works best. That rules out 90 (and 90.6) as favorable to best font rendering. Values below 96 are not recommended except when accurate matching of physical screen pixel density and Xorg/KDE DPI is a priority. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

When I change 'hinting style: full' to: 'hinting style: None' Then the underscores become visible.
What about with slight? and medum? Among the four choices, do you have a preference? What about changing the sub-pixel rendering to any of the other options? Can you try using analog ports instead of digital to see if it makes any difference? (In reply to comment #16)
The displays I am using are: - Philips 180P2 - Dell 1907FP
I have no exact matches. My only 1280x1024 in 19" is a Samsung 914V. My only 1280x1024 Dell is 17". Everything else except my Vizio TV that I can't rotate 90 has higher physical pixel density. I do opine what you see is likely to be difficult to reproduce except at lower than 96 ppi physical screen density. Asking elsewhere may be the best thing to do, support for e.g. Nvidia support or fontconfig mailing list, to see if you can find anyone who can reproduce outside of openSUSE users or devs. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
